- An inhibitor was added to an enzyme and the expected rate of the reaction was not detected and the substrate was not utilized at all. This inhibitor is (choose one answer only): Is un-competitive, meaning the inhibitor binds to a site near the active site. Is competitive, meaning the inhibitor binds directly to the same active site as the subtrate. Is non-competitive, meaning the inhibitor binds to site other than the active site as the subtrate. Is irreversible, meaning the inhibitor binds covalently to the enzyme keeping the enzyme inactive permanently.arrow_forwardMost efficient enzyme isarrow_forwardAn organic molecule that catalyzes a chemical reaction, without itself becoming used up or consumed, is the correct definition for which of the following terms? the substrate the enzyme the reactant the ligand the productarrow_forward
