Enzymes are either proteins or RNA molecules ( ribozymes ). Proteins are one of the major biomolecules; the others are carbohydrates (especially, polysaccharides ), lipids, and nucleic acids. Enzymes that are proteins in nature are polymers of amino acids.

Enzymes are reusable. Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.Find the Nike Enzyme Droptail (NFL Cowboys) Men's T-Shirt at Nike.com.
