B) Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP production, and how that is an e
suter [353]

Answer: B)

B) ADP can act as an allosteric activator by slowing the breakdown of fuel molecules if sufficient energy is in the cell. APT can act as an inhibitor by storing resources in more complex molecules. That is an example of feedback inhibitor because when the end product of the substrate is finished, it can bind to the allosteric site, which will result in the enzymes active site no longer being able to bind with the new substrates. And that is responsible for ATP production because That “stops” the enzyme from making more than necessary and thus wasting chemical resources.

C) Feedback inhibition is a method of metabolic control in which the need of the product of a metabolic that way acts as an inhibitor of an enzyme within that pathway. The APT generating path is an example of feedback inhibition because it controls the amount needed of the product and acts as an inhibitor of the enzyme in the anabolic  pathway.
