But once equilibrium is actually established, the same concentrations of products and reactants are formed in the catalyzed case as that uncategalyzed case. Now, let's discuss something called the maximum velocity of enzymes. So the maximum velocity of enzymes basically describes the maximum activity at which the enzyme will actually operate. So let's suppose in our mixture, we have a total of 100 enzymes, and each one of these enzymes will have its own active site. Now, if we add 50 substrate molecules, that only 50 enzymes will contain active sites that are filled. And that means our entire mixture, because only half of the enzymes are filled, the entire activity of all the enzymes will be half of its maximum value.
