Which type of inhibitor can be overcome completely by the addition of more substrate?

Question

Quizplus · Accepted Answer

Competitive inhibitors bind to the active site of the enzyme, preventing substrate binding. However, if the concentration of substrate is increased, it can outcompete the inhibitor for the active site, allowing the enzyme to function normally. Therefore, competitive inhibition can be overcome by adding more substrate. Irreversible inhibitors cannot be overcome by adding more substrate, as they form strong covalent bonds with the enzyme. Noncompetitive inhibitors bind to a site other than the active site, so adding more substrate does not affect their binding. Prosthetic inhibitors are noncovalently bound to an enzyme and do not affect its activity. Isotonic is not a type of inhibitor.
