Labeling the nephron function system. (The diagram is in the picture)
What is the mechanism of urine formation in the nephron?There are three important events in the formation of urine, namely filtering (filtration), absorption (reabsorption), and collection (augmentation).
The process of filtration occurs between the glomerulus and Bowman's capsule. When blood from the afferent arterioles enters the glomerulus, blood pressure is high. This causes water and molecules that are not dissolved in the blood to pass through the capillary walls of the glomerulus. Then, water and its molecules enter the filtration plate of Bowman's capsule. The result of this filtration is called glomerular filtrate or primary urine. The concentration of fluid as filtered enters the glomerulus is 300 mOSM, 100 percent by volume.
When the filtrate is removed, the blood in the glomerular efferent arterioles becomes very concentrated. This happens because the loss of so much water. In addition, the filtrate contains large substances that cannot pass through the glomerular capillary walls, such as blood cells, large proteins, and fat fragments. So that the volume of liquid is reduced to 30 percent. While the concentration of dissolved substances is still 300 mOSM
Meanwhile, primary urine, which is produced from Bowman's capsule, enters the proximal convoluted tubule. At the junction points between the capillaries surrounding the tubules, glucose and amino acids and Na+ ions are absorbed. The primary urine that enters the loop of Henle is already more isotonic with the blood in the capillaries. In the loop of Henle absorption of NaCl and water occurs. Absorption continues in the distal convoluted tubule. This is where the absorption of urea, creatinine, medicinal ingredients, H+, and NH4 – occurs. Meanwhile, NaCl salt and water and HCO3 ions - are re-absorbed. The results of this reabsorption contain water, salt, urea, and bile pigments which give urine its odor and color.
Enters the collecting tubule. In these tubules, water, NaCl salts, and urea are still being reabsorbed so that urine is formed which must be excreted from the body. From the collecting tubules, urine enters the renal pelvis, then flows down the ureters to the bladder (urinary bladder). When the bladder is full, the person will feel the urge to urinate.

the binding of calcium to troponin a) causes cross-bridges to detach b) changes the shape of the thick filament c) moves tropomyosin away from binding sites d) initiates an action potential across the sarcolemma e) produces energy for the power strok
The correct answer is c) moves tropomyosin away from binding sites.
What happens when calcium binds to troponin?
Tropomyosin is eliminated from the binding sites when calcium binds to troponin, changing the structure of the protein. When a muscle cell is triggered, the sarcoplasmic reticulum releases the calcium ions it has been holding in reserve, which allows the cross-bridge muscle contraction cycle to occur.
When troponin is activated, Ca2+ binds to it and causes azimuthal migration of tropomyosin around the actin filament, revealing the myosin binding sites and allowing the actin-myosin interaction that drives contraction.
Therefore, the binding of calcium to troponin moves tropomyosin away from the binding sites.

which two forms of transport require proteins found in the cell membrane to move material in and out of a cell?
The two main kinds of membrane transport proteins are carrier proteins and channel proteins.
There are typically two types of transport carried out by transport proteins: "facilitated diffusion," in which a substance is simply allowed to diffuse down its concentration gradient, and "active transport," in which a cell uses energy to move a substance in the opposite direction of its concentration gradient.
The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane. Facilitated diffusion is the method by which these molecules travel across the membrane with the aid of specific transport proteins. These distinct proteins are connected to what are known as channel proteins or carrier proteins (Figure below).

Explain how ATP and creatine phosphate function in skeletal muscle fiber contraction.
In a muscle at rest, extra ATP converts creatine into ADP and creatine phosphate by transferring its energy. This serves as a source of energy that may be swiftly drawn upon to produce further ATP.
Creatine phosphate transfers its phosphate back to ADP to form ATP and creatine when the muscle begins to contract and needs energy.
ATP provides the necessary energy for muscular contraction. The active-transport Ca++ pumps in the SR are powered by ATP, which also plays a direct role in the cross-bridge cycle. Without enough ATP, muscle contraction is impossible. Only a few seconds' worth of muscular contractions can be powered by the tiny quantity of ATP that is stored in muscle. To enable persistent contraction, ATP must be rapidly created and supplied as it is depleted.
