Theory
Enzymes are proteins that accelerate biochemical transformations by lowering the activation energy of reactions. Enzymes lower the activation energy for various biochemical reactions. They do this by binding the reactant(s), known as the substrate(s), to an active site within the enzyme. At the active site, the substrate(s) can form an activated complex at lower energy. Once the reaction completes, the product(s) leaves the active site, so the enzyme is free to catalyze more reactions.
