WebAug 5, 2024 · Enzymes, however, reduce the value of activation energy for a reaction, thereby phenomenally increasing the rate of reactions. Some enzymes lower the activation energy after the enzyme forms a complex with the substrate which by bending substrate molecules in a way facilitates bond-breaking. WebEnzymatic action can aid this process. The enzyme-substrate complex can lower the activation energy by contorting substrate molecules in such a way as to facilitate bond-breaking, helping to reach the transition state. Finally, enzymes can also lower activation energies by taking part in the chemical reaction itself.
