WebAug 17, 2024 · Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a ... WebEnzymes do affect the activation energy. The activation energy is the difference in free energy between the substrate and the transition state. The transitions state is the …
WebIt is important to remember that enzymes do not change the reaction's ∆G. In other words, they do not change whether a reaction is exergonic (spontaneous) or endergonic. This is because they do not change the reactants' or products' free energy. They only reduce the activation energy required to reach the transition state (Figure 6.15).
