WebReactions with a high activation energy will proceed very slowly, because only a few molecules will obtain enough energy to reach the transition state – even if they are highly exergonic. In the figure above, the reaction from X->Y has a much greater activation energy than the reverse reaction Y->X. WebEnzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently. Image modified from …
