試題詳解

29. 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 Km would be altered and Vmax would be decreased. Competitive inhibitors usually interact with the enzyme at the binding site for a substrate.
