Carbonic anhydrase catalysis Even a reaction as simple as the hydration of carbon dioxide is catalyzed by an enzyme namely,carbonic anhydrase(脱水酶). Carbonic anhydrase CO2+H2O H.CO; substrates Products The transfer of CO,from the tissues (组织)into the blood(t血液)and then to the alveolar(肺泡的)air would be less complete in the absence of this enzyme.This catalyzed reaction is 107 times as fast as the uncatalyzed one.Carbonic anhydrase catalysis Even a reaction as simple as the hydration of carbon dioxide is catalyzed by an enzyme namely, carbonic anhydrase (脱水酶).
