Enzymes •Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions.• In enzymatic reactions, substrates is converted into products.•Enzymes are selective for their substrates and speed up only a few reactions from among many possibilities.
Characteristics •lowering the activation energy. As a result, products are formed faster and reactions reach their equilibrium state more rapidly.•Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions.•As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions.•highly specific for their substrates.•A few RNA molecules called ribozymes also catalyze reactions
