And this is what we do in part three. So we can also use the Michael's Methane equation to describe the enzyme activity towards the end of that reaction. So when the substrate concentration is very, very high. So now we're basically going to use the same argument as in this case, but we're going to reverse because at the end of the reaction so when we have a very, very high concentration of substrate that means the Km value is much smaller than the substrate concentration. So for example, if we're somewhere here along the X axis, this quantity, this concentration is much higher than Km. And so what that means is towards the end we see that the concentration of S is much, much higher than the value of Km.
