The Kcat is lowered. The Kcat, the turnover number is lowered. And what that basically means is the efficiency of that active side in transforming the substrate into that particular product is decreased. And this makes sense why well, because as it turns out, when that enzyme binds onto that inhibitor, that inhibitor changes the shape of the active side. And so the active side is essentially no longer complementary to that particular substrate. And although the substrate can bind to that active side just as likely as in the case of the absence of the inhibitor, once the substrate binds onto this enzyme inhibitor complex, that fit Will not be perfect.
