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).
As a result, a catalyst also increase the rate of the chemical reacti- on, or makes the products form faster. 2)Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.
