Now, there are three different types of reversible inhibition processes. We have competitive inhibition, we have non competitive as well as non competitive. And actually, there's a fourth type known as mixed inhibition, but we're not going to focus on that one in this lecture. So let's begin by discussing each one of these processes, beginning with competitive inhibition. Now, in competitive inhibition, our inhibitor molecule, or ion, actually binds to the active side of that enzyme because the structure of our inhibitor actually resembles the structure of our substrate. Now, since the active side is occupied by that inhibitor, that means momentarily our enzyme will no longer be active and that substrate will no longer be able to bind into the active side of the enzyme because that inhibitor will be found inside that active side.
