Enzymes are chiefly proteins, that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the procedure are called substrates, and the enzyme converts them into different molecules, called the merchandises. Almost all procedures in a biological cell need enzymes to happen at important rates. Catalytic power and specificity are the two features…
