And so we can bring that out of our equation. And then we get K minus one plus K cat multiplied by the concentration of Es. And so now if we solve for K minus one plus Kcat divided by K one, we get the following result. So we simply rearrange this equation and we get this. Now this is the quantity that we defined previously as the K and the Mcales constant. So we said that the Michael is constant is equal to this ratio here.
