All of the following statements about competitive inhibition are correct EXCEPT: A) Competitive inhibitors are often chemical analogs of the substrate. B) For a group-specific enzyme, one substrate would be a competitive inhibitor of reactions of the other possible substrate. C) Sometimes a product of an enzyme-catalyzed reaction is a competitive inhibitor of its own production. D) In the presence of a competitive inhibitor, the apparent K_m would be altered and V_max would be decreased. E) Competitive inhibitors usually interact with the enzyme at the binding site for a substrate.

Question

Quizplus · Accepted Answer

Competitive inhibition affects the apparent Km (it increases), indicating that a higher substrate concentration is needed to reach half the maximum velocity. However, Vmax remains unchanged because the inhibition can be overcome by increasing the substrate concentration.
