A) Noncompetitive inhibitors are sometimes involved in feedback inhibition.
B) Noncompetitive inhibitors can serve a regulatory role in the body.
C) Noncompetitive inhibitors do not bind to the active site of an enzyme.
D) Increasing the concentration of a substrate restores function of an enzyme in the presence of a noncompetitive inhibitor.

Question

Quizplus · Accepted Answer

Increasing the concentration of a substrate does not restore the function of an enzyme in the presence of a noncompetitive inhibitor because these inhibitors bind to a different site, not the active site, and change the enzyme's shape, affecting its function regardless of substrate concentration.
