A.Cooperative inhibition B.Allosteric inhibition C.Feedback inhibition D.Metabolic inhibition

Answer 1

Answer:

Option C) Feedback inhibition

Feedback inhibition is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step in the pathway.

Explanation:

Feedback inhibition is a regulatory mechanism in which a biochemical pathway is regulated by the amount of the product that the pathway produces. Thus, it is also known as end-point inhibition.

For example:

The accumulation of ATP inhibits the action of phosphofructokinase, the enzyme that catalyzes the rate-limiting step of glycolysis
