Enzymes are specific for one set of substrates or a group of similar substrates.
Enzymes can only increase the rate of chemical reactions that would normally occur. They cannot cause a chemical reaction to occur that would not occur in its absence. Enzymes do not change the equilibrium of a reaction. They increase the rate of both the forward and reverse reactions, and therefore increase the rate at which equilibrium is reached. Enzymes are not changed in the reaction.
