Respuesta :
Activation energy is the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction. Enzymes speed up reactions by lowering activation energy.
Explanation:
Activation energy is defined as the minimum amount of energy necessary to initiate a chemical reaction.
Protein molecules that function like a catalyst are known as enzymes. Enzymes help in carrying a biochemical reaction without itself getting consumed.
Enzymes bind at the specific site of a substrate and helps in lowering the activation energy so that, more and more reactant molecules can participate in the reaction. As a result, formation of products become more rapid.
