The denominator is approximately equal to this. And now these two quantities cancel out and we simply see that V Naught is equal to V max. So what that means is as we continually add concentration of as we continually increase the concentration of S, eventually our V knot will be the V max. And once we reach the V max, it doesn't matter if we add more of that substrate. Adding more substrate will not have any effect on the rate of that enzyme catalyzed reaction. And that can be seen from this equation.
