<u>Answer</u>:
Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.
<u>Explanation</u>:
The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.
Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.
