Carbonic anhydrase catalyzes the hydration of CO2 (CO2 ? H2CO3 ). The Km of the enzyme for CO2 is 12 ?M. Carbonic anhydrase gave an initial velocity V0 = 4.5 ?M sec-1 when [CO2] = 36 ?M. What is Vmax of the reaction with this enzyme?1) 3 ?M sec-1 2)1 ?M sec-1 3)6 ?M sec-1 4)5 ?M sec-1 5) 2 ?M sec-1

Explain the two roles of the enzyme carbonic anhydrase (CAH) as it relates to two of the primary functions of the kidney?
