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.
