enzymes catalyze chemical reactions by
removing waste products
acting as substrates
generating heat
lowering the activation energy of the reaction

lowering the activation energy of the reaction

Explanation:

The enzymes are also called catalysts. The activation energy is the amount of energy needed by any reaction to start that reaction. Thus, the minimum amount of energy required to catalyze the reaction is activation energy.

The less amount of activation energy, more is the catalyzes by the enzyme used in the reaction. This shows increase in the rate of the reaction.
