Question

In a biochemical reaction, an enzyme acts as a catalyst, causing the
(1) activation energy of the reaction to decrease
(2) potential energy of the reactants to decrease
(3) kinetic energy of the reactants to increase
(4) heat of reaction to increase

Answer 1

The question says, in biochemical reactions, enzymes acts as catalyst causing the............. The correct option is A. The minimum energy that must be overcome before a chemical reaction occur is activation energy. Enzymes act as catalyst to lower the activation energy so that the biochemical reaction can occur.
