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. WebAug 28, 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 … can hydroxyzine cause night sweats

What is activation energy and how do enzymes affect it?

WebHow Do Enzymes Affect Activation Energy. Enzymes are usually proteins that act like catalysts. The enzyme's ability to make the reaction faster depends on the fact that it stabilizes the transition state. The transition state's energy or, in terms of a reaction, the activation energy is the minimum energy that is needed to break certain bonds ... WebThis works in animals and plants as well. Enzymes help reduce the activation energy of the complex molecules in the reaction.
