So the pathway that we take when we go from the reactant to the products does not actually determine, does not change what the Gibbs free energy is. It doesn't matter if we take pathway one, two or three when we go from the reactants to products, gives free energy will not actually change. So if we, for example, compare a reaction that has an enzyme and that same reaction that is uncatalyzed does not have an enzyme, the Gibbs free energy in those two reactions will be exactly the same. So a catalyzed and an uncatalyzed reaction will have the same exact Gibbs free energy value. And that leads us to a very important point. Enzymes, when they act on chemical reactions, they do not affect the Gibbs free energy value.
