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 biological catalysts, meaning that they are molecules capable of speeding up chemical reactions. They are large, protein-based compounds that bind to the reactants in a chemical reaction and, through one or more mechanisms, assist in the reaction without being changed at all themselves.Because chemical reactions are so diverse, the mechanisms by which enzymes speed up chemical reactions are also varied.hey are large, protein-based compounds that bind to the reactants in a chemical reaction and, through one or more mechanisms, assist in the reaction without being changed at all themselves.
