Question

The role of an enzyme in a reaction is to

• A. increase potential energy
• B. increase activation energy
• C. decrease activation energy
• D. both a and b depending on the substrate

Answer 1

The correct option is C decrease activation energy

The minimum amount of energy provided for a chemical reaction to happen is called activation energy. The rate of reaction increases with decrease in activation energy. The role of an enzyme is to decrease the activation energy of the reaction making the transition of substrate (S) to product (P) more easily as shown below.
