Assume the Km of one variant of carbonic anhydrase is 100M. First imagine an experiment employing 10 test tubes. Thetest tubes are all filled with 100 ml water. Imagine that thedifferent test tubes have different concentrations of CO2 rangingfrom 0.001 mM to 10 mM CO2. Initially there is NO enzyme in any ofthe test tubes. Now imagine that the test tubes are filled withwater and a significant amount (say 10 mM) of the enzyme carbonicanhydrase in each test tube.
