Regulation of isoleucine synthesis is an example of feedback inhibition of an anabolic pathway. With that in mind, explain how ATP might be involved in feedback inhibition of a catabolic pathway.

Answer & Explanation:

Feedback is a form of regulation where the main product of one reaction, can also inhibit it. It can work in several ways, mainly there's a receptor that, somehow, measures the presence of a determined molecule, in this case, ATP. These receptors can also be involved in the metabolic process and when there's an excess of ATP, the enzymes are inhibited, maybe with an allosteric type of inhibition.
