Question

Quizplus · Accepted Answer

Competitive inhibition can be overcome by adding more substrate, which increases the likelihood that the substrate will outcompete the inhibitor for binding to the active site. Noncompetitive inhibition is not as easily overcome, but it can be reversible if the inhibitor is removed from the system. So both competitive and noncompetitive inhibition are reversible, making option B the correct choice. Option A is incorrect because competitive inhibition can be reversed. Option C is incorrect because competitive inhibition is reversible. Option D is incorrect because noncompetitive inhibition can be reversible.
