Which mechanism reduces the energy needed for hydrolysis in enzymatic reactions?

A)Transition state stabilization
B)Substrate-level phosphorylation
C)Competitive binding inhibition
D)Allosteric enzyme activation

💡 Explanation

When an enzyme binds to a substrate, transition state stabilization lowers the activation energy because the enzyme's active site complements the transition state structure, reducing the energy required to reach that state. Therefore transition state stabilization results, rather than phosphorylation, inhibition, or activation, that would affect the reaction in other ways.
