Which of the following is a primary function of the active site of an enzyme? Select one: a. It catalyzes the reaction associated with the enzyme. b. It is activated by the presence of the end product of the metabolic pathway in which the enzyme is involved. c. It binds noncompetitive inhibitors of the enzyme. d. It binds allosteric regulators of the enzyme.

Which of the following BEST explains the role of enzymes in a reaction c. An enzyme binds to a product causing a decrease in the rate of the reaction. a. An enzyme causes an increase in the rate of reaction by binding to a substrate. d. An enzyme increases the temperature of a reaction so that the reaction can occur faster. b. An enzyme increases the amount of energy needed to complete the reaction.

An allosteric inhibitor does which of the following? a. Binds to an enzyme away from the active site and changes the conformation of the active site, increasing its affinity for substrate binding. b. Binds to the active site and blocks it from binding substrate. c. Binds to an enzyme away from the active site and changes the conformation of the active site, decreasing its affinity for the substrate. d. Binds directly to the active site and mimics the substrate.
The active site of an enzyme a. is identical to that of any other enzyme. b. is the part of the enzyme where the substrate can fit. c. can be used over and over. d. is where the coenzyme binds. e. Both b and c are correct.
