And so we see that the maximum rate at which the velocity operates is equal to K two multiplied by the concentration of enzyme where all the enzymes active sites are filled with the substrate. And if we take this equation and solve for if we solve for E total, we basically get E total is equal to D max divided by K two. And now we take equation eight and we replace E total with V max divided by K. If we plug this into here, the K two s will cancel and we're left with this equation here. So V Naught, which is the Y value on the following curve, is equal to V max, which is basically this maximum Y coordinate multiplied by the concentration of the substrate S divided by Km plus the concentration of substrate S and this is the equation that describes this blue curve. And notice in this equation, v max is a constant. It's simply this quantity that depends on the height of this red line.
