The lock-and-key model and the induced-fit model are two enzyme action models that explain both enzyme specificity and catalytic activity.
Emil Fischer hypothesized the Lock and Key model of enzyme action in 1899. According to Fischer, enzymes are highly specific to the substances with which they react. The substrate(s) bind to the enzyme at the active site, resulting in the formation of an enzyme-substrate complex.The enzyme speeds up the chemical reaction. This reaction can be a synthesis reaction (bond formation) or a digestion reaction (breaking bonds to form new substances).The enzyme releases the reaction's product(s). After completing a reaction, an enzyme can be reused. The Induced Fit model of enzyme structure provides a more accurate description of enzyme structure.Daniel Koshland proposed the Induced Fit model in 1958. The active site, according to Koshland's hypothesis, is shaped similarly enough and has specific chemical properties that attract a substrate to bind. When the substrate binds, the active site is prompted to change shape.

the reason that metabolizing cells are small in size is because
The reason that metabolizing cells are small in size is because the surface area of a cell must be able to accomplish nutrient/waste exchange.
Because cells are so small, they may maximise their surface area to volume ratio.
Smaller cells have a higher ratio, allowing more molecules and ions to pass through the cell membrane per unit of cytoplasmic volume.
Cells are so tiny because they need to be able to get nutrients in and waste out as rapidly as possible.
Their unique surface area in relation to the volume of cytoplasm enables them to control the exchange of certain molecules within the system.

why is it important to tetrapod hormonal function that, before aldosterone even evolved, one copy of the duplicated mineralocorticoid receptor (m receptor) lost the ability to bind aldosterone but retained the ability to bind cortisol?
The cortisol signalling is hampered if both versions of the receptor bind to both hormones.
The emergence of aldosterone would likely have interfered with cortisol signalling if both versions of the receptor could still bind both hormones.
The glucocorticoid receptor controls how the body will react to stress, even though cortisol is a blatant indicator that stress is present. A pathway that affects the production of specific stress-response proteins is activated when cortisol binds to the glucocorticoid receptor. The main mineralocorticoid hormone in tetrapod vertebrates is aldosterone, which is essential for controlling sodium transport across epithelia. The glucocorticoid hormones cortisol and/or corticosterone control metabolic processes.

Cellular processes are occurring in our bodies every second of every day. There are many mechanisms behind the methods of cellular transport. Your task is to read each case summary and determine a suspect based on evidence.
Possible Suspects: Osmosis Sally, Maggie Diffusion, Jenny Active Transport
Crime Description:
The suspect was reported to have quietly entered “CellBuck’s Coffee House” which was sparsely populated on that foggy Saturday morning on March 17, 2012. The first witness reported that the suspect glided into the establishment like a ghost. The suspect was reported to have floated about the room spreading her aromatic charm. The suspect is accused of stealing Mike Hematocyte’s wallet as she charmed him with her hypnotic aroma. The men that she touched during this experience were reported to have been so mesmerized that they could not recall her features. The female witness stated that just before she left, it was as if she was a magician floating through the air as she disappeared from the establishment back into the foggy mist.
The suspect based on evidence is Maggie Diffusion.
What evidence proves that?
The description of the suspect "gliding into the establishment like a ghost" and "floating about the room spreading her aromatic charm" suggest a passive and effortless movement, which is consistent with the mechanism of diffusion.
We know that during diffusion, substances move from an area of high concentration to low concentration, without the use of energy.
Another evidence is the fact that the men who were touched by the suspect were reported to have been "mesmerized" and "could not recall her features" which also suggests a chemical or biological process at work, which could also be related to diffusion of a substance that affected their perception.

in the cardiac myocyte the phase of rapid depolarization is due to ___
Option B is correct. The step of rapid depolarization in the cardiac myocyte is brought on by a net inflow of positive ions, Na+, into the cell.
The five phases of the cardiac action potential are generated by the cardiovascular or venticular myocyte. Phase 0 is when rapid depolarization takes place. The output across the membrane of the cardiac cell experiences a quick change during this phase that only lasts for a very brief time. It happens as a result of a net flow, or capillary permeability, of Na+ ions into the heart's cells from outside the organ. Therefore, option B should be selected.

you examine a tissue sample under the microscope and discover that the tissue appears to be striated muscle. what can be concluded from this observation?
If a tissue sample appears to be striated muscle when examined under the microscope, several conclusions can be drawn from this observation:Striated muscle tissue and so on.
Striated muscle tissue is a type of muscle tissue that is characterized by its striped or striated appearance under the microscope. This striping is due to the arrangement of actin and myosin filaments within the muscle fibers. Striated muscle tissue is found in several locations in the body, including the skeletal muscles that move the body, the cardiac muscle of the heart, and the smooth muscle of some organs. Skeletal muscle is the only type of muscle tissue that can be consciously controlled, so if the tissue sample is skeletal muscle, this suggests that it is part of the musculoskeletal system that allows for voluntary movement. Cardiac muscle tissue is found exclusively in the heart, and its striated appearance is an indication that it is adapted for continuous, rhythmic contraction that is essential for maintaining a steady blood flow throughout the body. Smooth muscle tissue, although also containing actin and myosin filaments, appears non-striated under the microscope and is found in the walls of many organs such as the digestive tract, bladder, and blood vessels, where it plays a role in involuntary movements such as peristalsis and vasoconstriction.
