Question 1 2 pts How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction? by decreasing the free-energy change of the reaction catalyzed by the enzyme by binding to an allosteric site, thus changing the shape of the active site of the enzyme by binding to the active site of the enzyme, thus preventing binding of the normal substrate by binding to the substrate, thus changing its shape so that it no longer binds to the active site...
