Detailed explanation-1: -Definition. An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.
Detailed explanation-2: -Enzymes are chemical catalysts that accelerate chemical reactions at physiological temperatures by lowering their activation energy. Enzymes are usually proteins consisting of one or more polypeptide chains.
Detailed explanation-3: -Biological catalysts are called enzymes. There is, for instance, an enzyme in our saliva which converts starch to a simple sugar, which is used by the cell to produce energy, and another enzyme which degrades the excess lactic acid produced when we overexert ourselves.
