WebReaction coordinate diagram for an exergonic reaction. Although the products are at a lower energy level than the reactants (free energy is released in going from reactants to products), there is still a "hump" in the energetic path of the reaction, reflecting the formation of the high-energy transition state. WebThe enzyme does not lower the activation energy, what it does is provide an alternate route that is at a lower energy level, thus more molecules are able to react. Now those at a higher energy can still react via the route without the enzyme, but can also go the route of lower energy through use of the enzyme. 5 comments ( 17 votes) Upvote Downvote sparks pulley https://multiagro.org
