And what that means is the V max. So this Y value here is equal to so if we use this equation, K two multiplied by well, what has to be the concentration of this for this to be the VMAX? Well, when the enzyme substrate complex. So when all the active sites are occupied, that means this quantity, the concentration of this will equal to the total concentration of the enzyme. And that can be seen from this particular equation seven. So in this equation we see that when this value is equal to zero, that means all the enzymes active sites are filled with a substrate, because when this is equal to zero, this will equal to this.
