Enzymes are the biological molecules that are responsible for regulating the rate with which the chemical reactions are taking place inside the biological systems. They act as a catalyst i.e., speed up the rate of reaction but are never consumed up during the reaction. Enzymes are proteins in nature and they have a globular structure.
The specialized folding of the amino acids tends to form an active site on the enzyme. The substrate molecule binds itself with the active site and hence, an enzyme-substrate complex is formed. This ES complex is then catalyzed into product and the enzyme is regenerated. The enzymes also serve the role of lowering the activation energy.
Examples of Enzymes:
The living systems are composed of diverse enzymes each of which is specialized for a certain process. The pepsin is involved in digesting the proteins present in the stomach. The lipases are responsible for breaking down the lipid molecules and starch is being digested by the action of amylase.
Two genetically engineered enzymes are produced simultaneously from a series of chemical
