So if we set Km equal to the substrate concentration then this denominator can be simplified from Km plus this to simply the concentration of S plus the concentration of S, where Km has been replaced with the concentration of S. So V naught is equal to v max multiplied by this ratio. Now, the denominator can be combined to basically combine these two quantities. So it's as if we have x plus x and that gives us two x. So that means we have v max multiplied by the concentration of S divided by two multiplied by the concentration of S. And notice these two quantities can now be canceled out and we simply have v Naught is equal to v max divided by two. And this is a very important physiological it carries very important physiological meaning. What this tells us is when the Michael is constant is equal to the substrate concentration, that particular x value, we see that the rate of that enzyme, the velocity of that enzyme is exactly half of the maximum velocity of that enzyme.
