Detailed explanation-1: -Catalysts make this process more efficient by lowering the activation energy, which is the energy barrier that must be surmounted for a chemical reaction to occur. As a result, catalysts make it easier for atoms to break and form chemical bonds to produce new combinations and new substances.

Detailed explanation-2: -Enzymes work by lowering the activation energy needed to start biochemical reactions. The activities of enzymes depend on the temperature, ionic conditions, and the pH of the surroundings.

Detailed explanation-3: -Catalysts do not alter the energy change between the products and reactants. Catalysts lower the activation energy for the reaction. Catalysts increase the forward rate, while reducing the reverse rate. Catalysts will not alter the equilibrium of the reaction.
