How Does a Noncompetitive Inhibitor Decrease the Rate of an Enzyme-Catalyzed

question 61

Multiple Choice

How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction?

• A) by binding to the active site of the enzyme, thus preventing binding of the normal substrate
• B) by binding to an allosteric site, thus changing the shape of the active site of the enzyme
• C) by decreasing the free-energy change of the reaction catalyzed by the enzyme
• D) by binding to the substrate, thus changing its shape so that it no longer binds to the active site of the enzyme
