So by increasing the concentration of the green molecules we increase the likelihood that the green molecules will collide with the active site to form the enzyme substrate complex. And that's exactly why if we increase the concentration of the substrate those green molecules will eventually outcompete these red inhibitor molecules and that will bring back the velocity of that velocity or the rate of that enzyme back to its normal value. So once again, competitive inhibitors typically have a much higher thinly for the active side than natural substrate molecules. However, if we increase the concentration of the substrate the additional substrate can outcompete the inhibitor for the active side. Therefore, increasing the substrate concentration can remove the effect of that competitive inhibitor that it has on that enzyme. And this is only true in competitive inhibition.
