Which of the following statements is true of noncompetitive inhibitors?
A) They slow down the rate of reaction.
B) They increase the efficiency of an enzyme.
C) They have no effect on the shape of the enzyme.
D) They increase the activity of an enzyme.

Question

Quizplus · Accepted Answer

Noncompetitive inhibitors bind to a site on the enzyme other than the active site, causing a conformational change in the enzyme that reduces its activity. This results in a slower rate of reaction, and does not increase the efficiency or activity of the enzyme. Noncompetitive inhibitors also do not affect the shape of the enzyme's active site.
