9. Explain what is meant by the statement "Metabotropic receptors act via second messengers."
10. Explain why it is the receptor and not the neurotransmitter that determines whether the postsynaptic membrane produces an EPSP or an IPSP.
11. A kangaroo is able to increase greatly its rate of movement on a flat surface without appreciable cost of transport. Yet, when it is forced to jump uphill, its oxygen consumption spikes tremendously. Why is this?
12. How do motor units regulate the force of muscle contraction?
13. Why doesn't a muscle continue to contract once the calcium is released?
14. Why don't postsynaptic membranes continue to depolarize after a neurotransmitter binds to their receptors?
The statement "Metabotropic receptors act via second messengers" means that the receptor itself does not act as an ion channel.
Instead, it is coupled to a G protein, which in turn activates an enzyme that produces a second messenger. The second messenger then acts on ion channels or other intracellular targets to produce an effect. The receptor, not the neurotransmitter, determines whether the postsynaptic membrane produces an EPSP or an IPSP. This is because the same neurotransmitter can bind to different types of receptors, each of which may produce a different effect. For example, acetylcholine can bind to nicotinic receptors, which produce EPSPs, or muscarinic receptors, which produce IPSPs.
When a kangaroo is forced to jump uphill, its oxygen consumption spikes tremendously because uphill jumping requires much more work than flat surface movement. The kangaroo must overcome the force of gravity, which requires energy. Additionally, the kangaroo must accelerate its body upwards, which requires additional energy. Motor units regulate the force of muscle contraction by varying the number and size of muscle fibers they innervate. A motor unit consists of a motor neuron and all the muscle fibers it innervates. When a motor neuron fires, all the muscle fibers in its motor unit contract. The force of contraction depends on the number of muscle fibers contracting and the frequency of motor neuron firing.

With increasing age, the heart must work harder to move the blood effectively because________.
The reason why with increasing age, the heart must work harder to move the blood effectively is because the arteries become harder and less elastic, causing the heart to pump harder to circulate blood.
As an individual grows older, the arterial system that transports blood from the heart to other body tissues starts to develop several conditions that make it harder for the heart to move blood effectively. The most significant problem that arises with age is the hardening and reduced elasticity of arteries.The hardened arteries have a smaller diameter, which makes it harder for the blood to move through them, so the heart must work harder and pump blood with greater force to move it through the circulatory system. This leads to an increase in blood pressure, and if left untreated, it may result in life-threatening conditions, such as heart disease and stroke.

1. Outer portion of the kidney (Cortex): The cortex is the outer region of the kidney that contains numerous nephrons, which are the functional units responsible for urine production. It is involved in the filtration of blood and the initial processing of urine.
2. Middle portion of the kidney (Medulla): The medulla is the inner region of the kidney, situated beneath the cortex. It consists of renal pyramids, which are cone-shaped structures that contain collecting ducts. The medulla plays a role in concentrating the urine and maintaining the osmotic balance of the body.
3. Site of blood filtration (Glomerulus): The glomerulus is a network of small blood vessels located within the renal cortex. It is responsible for the initial filtration of blood, where water, ions, and small molecules are filtered out of the bloodstream and into the renal tubules.
4. Site of most reabsorption and secretion (Proximal tubules): The proximal tubules are a part of the nephron located after the glomerulus. They are responsible for the reabsorption of most filtered substances, such as water, glucose, amino acids, and ions, back into the bloodstream. They also play a role in the secretion of certain substances into the tubular fluid.
5. Collects reabsorbed nutrients (Pertubular capillaries): The peritubular capillaries are a network of tiny blood vessels that surround the renal tubules. They collect the reabsorbed nutrients and substances from the tubular fluid and return them to the bloodstream for circulation to other parts of the body.
6. Measure of a solution's contents compared to water (Specific gravity): Specific gravity is a measure of the concentration of solutes in a solution compared to pure water. In the context of urine, it reflects the density of dissolved substances and can be used to assess hydration status and kidney function.
7. Structure for concentrating the urine (Nephron loop): The nephron loop, also known as the loop of Henle, is a U-shaped structure in the nephron that extends from the cortex into the medulla. It plays a crucial role in creating a concentration gradient in the kidney, which is essential for the reabsorption of water and the concentration of urine.
8. Causes an increase in sodium reabsorption (Aldosterone): Aldosterone is a hormone produced by the adrenal glands. It acts on the renal tubules, specifically the distal tubules and collecting ducts, to increase the reabsorption of sodium ions and water while promoting the excretion of potassium ions. It helps regulate fluid balance and blood pressure.
9. Causes increased sodium secretion (ANP): ANP (Atrial Natriuretic Peptide) is a hormone produced by the heart. It acts on the renal tubules to inhibit the reabsorption of sodium and water, leading to increased sodium excretion and urine production. ANP helps regulate blood volume and blood pressure by promoting the elimination of excess fluid from the body.

Question 7
"The hormone glucagon causes the release of of glucose (sugar) from body cells into the bloodstream. Its secretion is controlled by a negative feedback system between the concentration of glucose in the blood and the glucagon-secreting cells in the pancreas. Therefore, which of the following statement is correct?"
O"A decrease in blood glucose concentration stimulates glucagon secretion, which in turn further lowers the blood glucose concentration."
O"An increase in blood glucose concentration stimulates glucagon secretion, which in turn lowers the blood glucose concentration
O"A decrease in blood glucose concentration sulates glucagon secretion, which in turn increases the blood glucose concentration.
O"An increase in blood glucose concentration inhibits glucagon secretion, which further increases the blood glucose concentration.
Cortisol decreases the rate of glycolysis. This statement is true.
The correct statement among the given options is: "A decrease in blood glucose concentration stimulates glucagon secretion, which in turn further lowers the blood glucose concentration."
The hormone glucagon is produced in the pancreas. It plays an important role in glucose metabolism. When the glucose level falls in the bloodstream, the alpha cells of the pancreas release glucagon. Glucagon then activates the liver to produce and release glucose. This restores the glucose levels in the bloodstream to normal.
This mechanism is known as the glucagon axis. It is a negative feedback mechanism.Glucagon secretion is regulated by a negative feedback mechanism. The concentration of glucose in the bloodstream is the factor that regulates the secretion of glucagon. When the glucose level falls, it stimulates the secretion of glucagon. The glucagon, in turn, stimulates the liver to produce and release glucose.
This mechanism reduces the glucose demand of the body. As a result, the concentration of glucose in the bloodstream decreases. Therefore, the statement, "A decrease in blood glucose concentration stimulates glucagon secretion, which in turn further lowers the blood glucose concentration," is correct.

How
does a muscle contract, and how does this lead to movement of a
bone?
Muscle contraction occurs through the sliding filament theory, where myosin and actin filaments interact within muscle cells. When a nerve impulse reaches the muscle, it triggers the release of calcium ions, allowing myosin heads to bind to actin filaments.
This binding initiates a series of cross-bridge formations and power strokes, causing the actin filaments to slide past the myosin filaments. This sliding movement shortens the sarcomeres, generating force within the muscle. The force generated is transmitted through tendons, connecting the muscle to bones.
As the muscle contracts, the pulling force on the bones leads to joint movement and overall skeletal motion. This coordinated process, regulated by the nervous system, allows muscles to generate the force necessary for movement and perform various tasks, such as lifting objects, walking, or running.

Select one:
A) Decreases elimination by effecting renal biotransformation
B) Decreases elimination by decreasing glomerular filtration
C) Does not affect elimination
D) Increases elimination by increasing metabolism
E) Increases elimination by trapping ions in the urine
E) Increases elimination by trapping ions in the urine
The administration of alkaline substances, such as sodium bicarbonate (NaHCO3), can affect the elimination of acidic drugs by increasing their elimination.
Ot is due to the process of ion trapping, which occurs in the kidneys.
When an alkaline substance is administered, it raises the pH of the urine, making it more alkaline. Acidic drugs tend to be weak acids that can become ionized in alkaline environments. In the kidney, the ionized form of the drug is less likely to be reabsorbed back into the bloodstream and more likely to remain in the urine, leading to increased elimination.
This process is known as ion trapping, where the ionized form of the drug becomes trapped in the urine due to the pH gradient between the urine and the blood. As a result, the elimination of acidic drugs is increased when the urine pH is made more alkaline.
It's important to note that this effect is specific to acidic drugs, as basic drugs would not undergo ion trapping in an alkaline environment. Additionally, the administration of alkaline substances may have other effects on drug metabolism and excretion, but the primary mechanism for the increased elimination of acidic drugs is through ion trapping in the urine.

What 3 layers make up the mucous membrane (aka mucosa)? Why is the lumen lined with stratified squamous epithelium? Where is the upper esophageal sphincter and how does it work? Where is the lower esophageal sphincter (gastroesophageal sphincter) and how does it work?
The three layers of the mucous membrane (mucosa) are the epithelium, lamina propria, and muscularis mucosae. The lumen is lined with stratified squamous epithelium to protect against mechanical and chemical damage.
The mucous membrane (mucosa) of the esophagus consists of three layers. The innermost layer is the epithelium, which lines the lumen. In the esophagus, the epithelium is composed of stratified squamous epithelial cells. This type of epithelium is well-suited to withstand the abrasion and mechanical stress of food passage.
The middle layer of the mucous membrane is the lamina propria, which contains blood vessels, lymphatic vessels, and glands. It provides support and nutrition to the epithelium. The outermost layer is the muscularis mucosae, a thin layer of smooth muscle that helps with the movement and folding of the mucosa.
The upper esophageal sphincter is located at the top of the esophagus, just below the pharynx. It consists of a circular band of skeletal muscle that contracts to close off the esophagus and prevent the entry of air into the digestive system. It opens during swallowing to allow the passage of food into the esophagus.
The lower esophageal sphincter, also known as the gastroesophageal sphincter or cardiac sphincter, is located at the junction between the esophagus and the stomach. It is a circular band of smooth muscle that helps prevent the backflow of stomach acid and contents into the esophagus. It normally remains closed to maintain the separation between the two organs.

A patient has a tumor on his posterior pituitary gland preventing its release of hormones. How would his ability to regulate his blood pressure be affected?
The patient's ability to regulate his blood pressure would be affected due to the tumor on his posterior pituitary gland that prevents the gland from releasing hormones.
What is the pituitary gland?
The pituitary gland is a tiny gland that is located at the base of the brain. It is also referred to as the hypophysis, and it plays a critical role in the body's hormonal system. The pituitary gland produces hormones that regulate and control several bodily functions. Hormones produced by the pituitary gland are released into the bloodstream and carried to various parts of the body.The pituitary gland is composed of two major parts, the anterior pituitary gland and the posterior pituitary gland.The anterior pituitary gland produces and secretes a broad range of hormones, whereas the posterior pituitary gland stores and releases only two hormones: oxytocin and antidiuretic hormone (ADH).What is a tumor?
A tumor is an abnormal mass of tissue that develops when cells in the body divide excessively, forming growths.Tumors can be either benign or malignant, depending on their nature. Benign tumors are non-cancerous, whereas malignant tumors are cancerous and can metastasize to other parts of the body.What happens if there's a tumor on the pituitary gland?
The hormones that are released by the pituitary gland control many of the body's most critical processes. Tumors on the pituitary gland can cause hormonal imbalances, leading to a variety of symptoms and complications that depend on the type of hormone that's being affected.In the case of a tumor on the posterior pituitary gland, the gland's ability to release hormones is hindered, resulting in the patient's inability to regulate their blood pressure. ADH, or antidiuretic hormone, is the hormone that regulates water balance in the body. It manages water reabsorption from the kidneys, maintaining the body's fluid balance. Without enough ADH, the body produces a large volume of urine, leading to dehydration, electrolyte imbalances, and high blood pressure.So, the patient's ability to regulate their blood pressure would be affected if they had a tumor on the posterior pituitary gland, resulting in a hormonal imbalance that could have a variety of negative effects on the body.Learn more about pituitary gland:

The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.
Individual I-1 is heterozygous (Aa) for the dominant trait. This is because they have a child (II-1) who is homozygous recessive (aa). The only way for this to happen is if individual I-1 is heterozygous.
What is the conclusion on the pedigree?Pedigree analysis: A pedigree is a diagram that shows the inheritance of a trait from parents to offspring. In this pedigree, the dominant trait is represented by a solid symbol and the recessive trait is represented by an open symbol.
Genotype: The genotype of an individual is their genetic makeup, or the combination of alleles that they have for a particular trait. The phenotype of an individual is their physical appearance, which is determined by their genotype and the environment.
Heterozygous: An individual is heterozygous for a trait if they have one dominant allele and one recessive allele. This means that they have the potential to express the dominant trait, but they may also express the recessive trait if they are in an environment that is not favorable for the dominant trait.
Homozygous: An individual is homozygous for a trait if they have two copies of the same allele for that trait. This means that they will always express the trait, regardless of the environment.

The phenomenon of flexor muscles of one leg being stimulated to contract in a flexor withdrawal reflex and the extensor muscles of the opposite leg are stimulated to support the weight suddenly shifted to it is known as crossed-extensor reflex.
Crossed-extensor reflexThis phenomenon is known as crossed-extensor reflex. The flexor withdrawal reflex occurs when the extensor muscle group of the opposite limb or the corresponding muscle group of the same limb is excited. A muscle stretch reflex is a reaction that occurs as a result of a sudden extension or stretching of a muscle. The tendon reflex is an automatic reflex that occurs as a result of a sudden strain on a muscle. Superficial reflexes are a form of motor response that occurs as a result of stimulation of the skin.
The correct order of the five essential components of a reflex arc is as follows:Sensory receptorSensory neuronIntegration center Motor neuron Effector organThe function of a sensory receptor is to detect a change and transform it into an electrical impulse. The electrical impulse is carried by a sensory neuron to the spinal cord or brainstem, where it connects with a motor neuron. Integration centers evaluate the input and formulate a response, which is carried by a motor neuron to an effector organ, which produces a response.

A sensory nerve fibre begins with the stimulation of a Pacinian corpuscle when a C. Rapid vibration is applied to the Pacinian corpuscle, and a graded receptor potential is generated.
A sensory organ with a focus on detecting mechanical stimuli like deep pressure or fast vibration is called the Pacinian corpuscle. The Pacinian corpuscle responds to rapid vibration by generating a graded receptor potential, where the magnitude of the receptor potential is directly inversely proportional to the strength of the stimulus. The size of the receptor potential grows as the vibration continues and more corpuscle receptors are made active.
At the first node of Ranvier, an action potential is produced when the receptor potential hits a threshold of 10 mV. The action potential, a short electrical signal that travels through the sensory nerve fibre and sends the sensory data to the central nervous system for additional processing, is a phenomenon that occurs in living things.

Selective NSAIDS work through the inhibition of which enzyme?
Cox-2
Cox-1
Both Cox-1 and Cox-2
Thromboxane
Selective NSAIDS work through the inhibition of Cox-2 enzyme. NSAIDs (nonsteroidal anti-inflammatory drugs) are a class of drugs that includes ibuprofen, aspirin, and naproxen. These medicines have the ability to relieve inflammation and pain while also lowering fever.
NSAIDs, on the other hand, operate by blocking two different forms of cyclooxygenase (COX) enzymes, namely COX-1 and COX-2. COX-1 enzymes are found in the stomach and help protect the lining of the stomach and intestines. The COX-2 enzyme, on the other hand, is primarily responsible for inflammation and pain. When the COX-2 enzyme is inhibited by NSAIDs, inflammation and pain are reduced. Thromboxane is a hormone that is produced by blood platelets and is associated with blood clotting. It also causes constriction of blood vessels, resulting in higher blood pressure.
