Web28 aug. 2024 · Enzymes lower the energy of activation by forming an enzyme-substrate complex allowing products of the enzyme reaction to be formed and released. Enzyme catalysed reactions occur at a particular place on the surface of the large enzyme molecule called the active site (as in heterogeneous catalysts). WebA catalyst lowers the activation energy by changing the transition state of the reaction. The reaction then goes through a different pathway/mechanism than the uncatalyzed reaction. The catalyst does not change the net energy difference between reactant and product.
