Enzymes lower activation energy at active site
Question asked:
“Enzymes create a reaction pathway with lower activation energy by interacting with the substrate at the active site, helping the substrate more easily reach the transition state.”
Summary
Enzymes lower the activation energy of a reaction by binding the substrate at the active site, stabilizing the transition state and facilitating its formation. This interaction creates a reaction pathway with reduced energy barriers, allowing the substrate to more readily reach the transition state.

The stress produced by such distortion of the substrate can further facilitate its conversion to the transition state by weakening critical bonds. Moreover, the transition state is stabilized by its tight binding to the enzyme, thereby lowering the required energy of activation.

Enzymes do not alter or shift the equilibrium of a given reaction but instead affect the free energy required to initiate a conversion, which affects the reaction rate. The energy hump that must be surmounted for a reaction to progress is called the activation energy; this is the highest energy on a reaction diagram.

Therefore, together with our previous analysis6 of diester hydrolysis in the AP enzymes, our QM/MM calculations provide further support to the hypothesis12,14 that AP enzymes are able to recognize and stabilize multiple types of transition state in a single active site.

Remember: all catalysts, enzymes included, accelerate reactions by lowering the energy of the transition state. With this in mind, it should make sense that the primary job of an enzyme is to maximize favorable interactions with the transition ...
- Which of the Following Statements is NOT True About Enzymes? (Exam Guide) - sdrfoundation.org
The claim that enzymes are consumed or permanently altered during a chemical reaction is not true. Enzymes function as biological catalysts that accelerate chemical processes by lowering activation energy while remaining completely unchanged themselves.
