Enzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).nzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).
The enzyme possibly works as like a test tube within which reagents meet to form products. Enzymes facilitate this meeting, making it easier for collisions between reagents to occur and, as a result, the activation energy of the chemical reaction is reduced. This is one possible hypothesis.
