But the enzyme does have an effect on the activation energy. In fact, what the enzyme typically does is it actually lowers the energy of that transition state. And by lowering the energy of the transition state, it makes this mountain smaller. And so this height will be smaller, and the delta g that gives the activation energy of that reaction will become smaller. And if we decrease the activation energy by essentially stabilizing that transition state, we will speed up the reaction, because ultimately, it's the activation energy, it's the energy barrier that determines the kinetics, the speed, and the rate of that chemical reaction. So enzymes do not affect the equilibrium.
