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 rate were measured by the disappearance of bicarbonate?
 
  Substrate Km (mM) Kcat (sec-1) Kcat/Km (m M-1sec-1)
  CO2
  HCO3- 12
  26 1106
  4105 8.3104
  1.5104
   a. CO2 would increase the activity of the enzyme
   b. CO2 would cause an apparent decrease in the Km for HCO3-
   c. CO2 would act as a noncompetitive inhibitor
   d. CO2 would act as a competitive inhibitor
   e. none of the above
