How does inhibition of an enzyme-catalyzed reaction by a competitive inhibitor differ from inhibition by a noncompetitive inhibitor?
A. Competitive inhibitors interfere with the enzyme; noncompetitive inhibitors interfere with the reactants.
B. Competitive inhibitors bind to the enzyme reversibly; noncompetitive inhibitors bind to it irreversibly.
C. Competitive inhibitors change the enzymes tertiary structure; noncompetitive inhibitors cause polypeptide subunits to dissociate.
D. Competitive inhibitors bind to the active site of the enzyme; noncompetitive inhibitors bind to a different site.
