試題詳解

30. Carbonic anhydrase has two substrates, carbon dioxide and bicarbonate, which are both converted to carbonic acid. Kinetic data for each is given below. While determining the kinetics of HCO3 as a substrate, how would the addition of CO₂ effect the reaction if the rates were measured by the disappearance of bicarbonate?

(A) CO₂ would increase the activity of the enzyme.
(B) CO₂ would cause an apparent decrease in the
(C) CO₂ would act as a noncompetitive inhibitor.
(D) CO₂ would act as a competitive inhibitor.
(E) None of the above is correct.
