So these reactants will move into the active side of that enzyme, creating the enzyme substrate complex. And what the enzyme actually does inside that active side is it stabilizes this partially broken bond and this partially formed bond. And by stabilizing these partially broken or formed bonds, it lowers the energy of activation. 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.
