And so what that means is the V max is equal to K two multiplied by the maximum value of the enzyme substrate complex concentration. And this maximum value can be a maximum of E total. So we replace this with this quantity here. 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.
