This is a zero Th order chemical reaction. And so what that means is this will cancel out because anything to the zero is one and so D equals K and V Naught is V and V max is the K value. And what that means is by changing the concentration, the substrate when we have a very high substrate concentration that will not affect the rate of that enzyme catalyzed reaction. So once again, this tells us that the velocity approaches a maximum as the substrate concentration increases. And this describes a zero order reaction. This means that increasing the substrate concentration will not actually affect the rate of that chemical reaction when we're very far along the X axis to the right.
