A new antibiotic has been developed.It acts as a noncompetitive inhibitor of an enzyme.How will this antibiotic affect delta G for the reaction that is catalyzed by the enzyme?

Question

Quizplus · Accepted Answer

A noncompetitive inhibitor does not bind to the active site of the enzyme, but instead binds to a different site on the enzyme, causing a conformational change that alters the enzyme's activity. The inhibitor does not affect the actual reaction or the equilibrium constant, so delta G, which is related to the equilibrium constant, will be unaffected.
