Which statement about noncompetitive inhibitors is FALSE?
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.
E) Binding of a noncompetitive inhibitor results in deformation of an enzyme's active site.

Question

Quizplus · Accepted Answer

Noncompetitive inhibitors bind to an enzyme at a site other than the active site, which alters the enzyme's shape and function. Increasing the substrate concentration does not overcome the inhibition caused by a noncompetitive inhibitor, because the inhibitor affects the enzyme's structure and function regardless of substrate concentration.
