試題詳解

63. During a metabolic pathway, the accumulation of a specific intermediate inhibits the activity of the pathway's first enzyme. This type of regulation is known as:
(A) Competitive inhibition, where the intermediate competes with the substrate for the active site.
(B) Non-competitive inhibition, where the intermediate binds to a different site on the enzyme.
(C) Feedback inhibition, where the intermediate acts as a regulator of the pathway.
(D) Allosteric activation, where the intermediate enhances the enzyme's activity.
