So once again, enzymes do not affect the free energy value of the products, nor will they affect the free energy value of the reactants. And since the energy value of the product and reactants will not be effective, that means the delta g, the difference between this and this will not be affected as well. Now, because it's the energy of the product and reactants. And specifically, it's the difference between the energy of the product and reactants that determines the concentrations of products and reactants that will exist at equilibrium. Because the enzymes do not affect the energy values of the products and reactants, they will not affect the concentration of the products and reactants that will exist at equilibrium. So once again, we know that enzymes do not affect the free energy of the reactants and products.
