The enzymes refer to the catalysts that enhance the rate of a chemical reaction without themselves going through any kind of permanent chemical modification. They neither appear as the reaction products nor are used up in the reaction.  

During the initial phase of a chemical reaction incorporating enzymes, the substrates combine themselves to the enzyme's active site. Once the suitable substrates combine with an enzyme to produce an enzyme-substrate complex, a chemical reaction between the substrates can take place.
