Which of the following is a primary function of the active site of an enzyme?
A) It binds allosteric regulators of the enzyme.
B) It binds noncompetitive inhibitors of the enzyme.
C) It catalyzes the reaction associated with the enzyme.
D) It is activated by the presence of the end product of the metabolic pathway in which the enzyme is involved.

Question

Quizplus · Accepted Answer

The primary function of the active site of an enzyme is to catalyze the reaction associated with the enzyme. The active site is a specific region of the enzyme where the substrate binds and where the chemical reaction takes place.

(A) is incorrect because allosteric regulators bind to regulatory sites on the enzyme, not the active site.
(B) is incorrect because noncompetitive inhibitors can bind to other sites on the enzyme, not just the active site.
(D) is incorrect because the end product of a metabolic pathway typically functions as an inhibitor or a feedback inhibitor, rather than activating the enzyme.
