It stabilizes the transition state, lowering that free energy of activation. And if we lower that free energy of activation, we increase the rate at which that reaction takes place. So, once again, enzymes bind specific substrates on regions called active sites to form the enzyme substrate complex. By binding substrates in the active sites, enzymes stabilize the energy of the transition state, which in turn stimulates the breakage of the old bonds and the formation of the new bonds to form that product molecule, as shown in this particular diagram. So if we look at the following diagram once more, when we go from the uncannyyzed to the catalyzed case, we see that the energy of the products or reactants is not changed. This energy is the same as this energy value, and this energy is the same as this energy.
