Like any other protein, enzymes are also made up of long chains of amino acids held together by peptide bonds. Enzymes play an important role in performing or controlling a host of chemical reactions that take place in the body. The induced-fit model is a model for enzyme – substrate interaction to describe that the substrate is capable of inducing the proper alignment of the active site of the enzyme, causing the latter to subsequently perform its catalytic function.
