Enzymes are biological catalysts which lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. The enzyme have active site which is the location on the enzyme surface where substrates bind, and where the chemical reaction catalyzed by the enzyme occurs. The chemical mechanisms that enzymes use to make it easier to get to the transition state are proximity, orientation, induced fitreactive amino acid group and coenzymes and metal ions. An enzyme catalysed reaction involving the formation of enzyme-substrate (ES) and enzyme-product (EP) complexes.
