Now, why does that actually take place? Well, recall what an uncompetitive inhibitor does. An uncompetitive inhibitor binds onto that side of the enzyme that is only created when the substrate actually binds onto that particular enzyme. So what that does is it decreases the total number of enzymes that are functional in the mixture. And so it brings down the V max value, decreases the V max value. Now, if the V max value is decreased, then the ratio one divided by smaller V max value means we have a Y intercept that is higher up.
