sis to speed up reactions. An enzyme catalyzes a reaction by lowering the E A barrier (Figure 8.13), enabling the reactant molecules to absorb enough energy to reach the transition state even at moderate temperatures. An enzyme cannot change the âG for a reaction; it cannot make an endergonic reaction exergonic. Enzymes can only hasten reactions that would eventually occur anyway, but this function makes it possible for the cell to have a dynamic metabolism, routing chemicals smoothly through the cellâs metabolic pathways. And because enzymes are very speciï¬c for
