ABSTRACT
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. The proteins in enzymes are usually globular. Enzymes break down food. Enzymes are the workhorses of the body. The enzymes break down the food into tiny particles which can be converted into energy in the body. The breakdown of food is an essential part of the conversion of food into energy. Holoenzyme is the term used to describe the whole enzyme molecule which may be composed of an enzyme protein and a coenzyme or a prosthetic group. An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Biocatalysis may be broadly defined as the use of enzymes or whole cells as biocatalysts for industrial synthetic chemistry. Immobilization is the process of adhering biocatalysts to a solid support.
