And that's a very important process. So DNA polymerase one has to be very careful in how it actually catalyzes that particular reaction. And so logically, it makes sense that DNA polymerase one has a lower turnover rate than carbonic and hydrase because all carbonic and hydrase has to do is take all those CO2 molecules produced by all the cells in our body and transform it into a bicarbonate molecule. So that we can actually store and dissolve that bicarbonate the CO2 molecule in our blood. Now, the final thing that I'd like to discuss is what we get if we take the reciprocal of the turnover number. So it turns out that if we take the K two value and we simply take the reciprocate, so we take one divided by Kcat, what that gives us is the time period that it takes a single active site of a single enzyme to actually transform a single substrate molecule into a single product.
