Carbonic anhydrase of erythrocytes ( r 30,000 ) has one of the highest turnover numbers known. It catalyzes the reversible hydration of CO2. H2O+CO2H2CO3 This is an important process in the transport of CO2 from the tissues to the lungs. If 18 g of pure carbonic anhydrase catalyzes the hydration of 0.40 g of CO2 in 1 min at 37 C at max , what is the turnover number ( cat ) of carbonic anhydrase?

cat= x10y min1
