Question

The glycolytic pathway oxidizes glucose to two molecules of pyruvate and also produces a net of two molecules of ATP. ATP allosterically inhibits the enzyme, PFK-1, that catalyzes the third step of glycolysis. This is an example of ________.

Answer 1

Feedback inhibition

Step-by-step explanation:

Feedback inhibition is the process in which end product of the reaction controls or inhibits action of enzyme which helped to produce it.

Phosphofructokinase (PFK-1) is the most important enzyme in the glycolytic pathway.

High levels of ATP allosterically in the liver inhibit the enzyme, thus lowering the affinity for fructose 6-phosphate. Thus, ATP which is produced as a end product of the glycolysis (series of reaction involving various enzymes and catalysts) inhibits the enzyme, PFK-1 which is used in the third step.
