So we have an exothermic reaction going this way and an endothermic reaction going in reverse. And we see that when the enzyme actually lowers the activation energy. So this is our uncatalyzed reaction that does not involve the enzyme. And this is the graph for the catalyzed reaction that does involve that enzyme. Remember, enzymes are basically catalysts. So we see that when we lower the activation energy, we not only lower the activation energy for the full reaction going this way, we also decrease the activation energy for the reverse reaction.
