Detailed explanation-1: -Enzymes lower the activation energy necessary to transform a reactant into a product.

Detailed explanation-2: -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: -Desolvation or taking reactants out of the solution state. Establishing weak bonds between the reactants and enzyme. Bringing the reactant molecules closer in the region of the active sites of enzymes. Development of strain in the bonds of the reactants by the electrophilic and nucleophilic attack.

Detailed explanation-5: –Enzyme brings the substrate to the correct orientation after attaching with that and due to this entropy of the reaction also reduces which also helps for lowering the activation energy. Due to the above given points enzymes lower the activation energy.
