Summary Introduction
To review:
The reason behind changes in the chemical composition of the enzyme only during catalysis and then retrieval of the same composition as before.
Introduction:
Enzymes make a reaction go faster. These molecules are either proteinaceous or nonproteinaceous. Most enzymes are proteins, and substrates are the molecules that the enzymes act on. In a reaction, the enzymes help turn reactants or the substrate into products by attaching the substrate to its active site. Every enzyme has a unique active site by the virtue of different amino acid combinations nesting within it. They will only bind to certain substrates and therefore they are highly “specific” in nature.
