And this makes sense because our tissues and cells produce a very, very large number of CO2 molecules. And so to effectively get rid of all those CO2 molecules, our body has to have a very effective and a very efficient enzyme. Now, to compare carbonic and hydrates to another enzyme, let's, for example, talk about DNA polymerase one. Now, DNA polymerase one has a turnover number of about 15. And so what that means is only 15 of the substrate molecules are transformed into the product molecules by DNA polymerase one every single second. So now the fact that carbonic anhydrase has a much higher rate than DNA polymerase one makes sense because DNA polymerase one is actually used in a very important process where we cannot make any mistakes because DNA polymerase one is used to replicate DNA molecules.
