Difference between the key and look model and induced fit modal

1.	Difference between the key and look model and induced fit modal
Answer» In this analogy, the\xa0lock\xa0is the enzyme and the\xa0key\xa0is the substrate. Only the correctly sized\xa0key\xa0(substrate) fits into the\xa0key\xa0hole (active site) of the\xa0lock\xa0(enzyme). The\xa0induced-fit\xa0theory assumes that the substrate plays a role in determining the final shape of the enzyme and that the enzyme is partially flexible.\xa0The\xa0induced fit model\xa0describes the formation of the E-S complex as a result of the interaction between the substrate and a flexible active site. The substrate produces changes in the conformation on the enzyme aligning properly the groups in the enzyme. It allows\xa0better\xa0binding and catalytic effects.
