Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.
Detailed explanation-2: -Enzymes allow activation energies to be lowered. Enzymes lower the activation energy necessary to transform a reactant into a product.
Detailed explanation-3: -They speed up biochemical reactions. Under the conditions inside living cells, biochemical reactions would occur too slowly to support life without the help of enzymes. Enzymes increase the rate of biochemical reactions by reducing the amount of activation energy needed for reactants to start reacting.
Detailed explanation-4: -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.
