So that is a very important point to remember about how the catalyst, our enzymes, basically lower the activation energy. Now let's move on to the second important point that we must always remember about enzymes, biological catalysts, that basically speed up reactions that take place within our bodies. So, although enzymes increase the rate of the reaction, although they do in fact affect the kinetics of the reaction, they do not affect the thermodynamics of that reaction. And what that means is the concentration of the products that are produced at the end of the catalyzed reaction is exactly the same as the concentration of products that are produced for the uncatalyzed reaction. So at equilibrium, for the catalyzed version, we still have the same exact concentrations of reactants and products that are left over and formed. So, although enzymes increase the rate of reaction, they do not increase or decrease how much product is actually formed.
