If Km increases, the Finity decreases. If Km decreases, the Finity increases. So what happens in the presence of the inhibitor? Well, when the inhibitor binds onto the enzyme substrate complex, what happens is once we form the enzyme substrate inhibitor complex, that inhibitor, by binding onto that complex, it prevents that substrate from actually leaving that active side. And what that means is, because that active side does not release that substrate, the affinity of that substrate for the enzyme increases. And if the affinity of that enzyme and if the affinity of the substrate for the active side of the enzyme increases, when the inhibitor binds into the complex, the Km value decreases.
