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).
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Reaction profiles: uncatalysed and enzyme-catalysed. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway.
