And each one of these are Irreversible inhibitors that modify the enzyme by binding covalently to that enzyme. Now let's move on to reversible inhibitors. So in reversible inhibition, we have these inhibitors that bind onto the enzyme, but they bind relatively weakly, and that means reversibly. So we can easily change the conditions in the environment and that will essentially cause the dissociation of that inhibitor from that particular enzyme. So the defining property of reversible inhibition is the ease with which the inhibitors can actually dissociate and break away from the enzyme under certain condition. And this is in contrast to Irreversible inhibitors that basically bind onto the enzyme.
