Detailed explanation-1: -Enzymes lower the activation energy necessary to transform a reactant into a product.
Detailed explanation-2: -Compare the activation energy with and without the enzyme. Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. For example: Enzymes bring reactants together so they don’t have to expend energy moving about until they collide at random.
Detailed explanation-3: -A catalyst increases the rate of reaction by decreasing the activation energy. Decreased activation energy means less energy required to start the reaction.
Detailed explanation-4: -By manipulating the substrates of the reaction, the enzyme can lower the necessary energy needed to make the reaction occur.
