Enzymes argon biological catalysts, which accele shop the rank of biochemical answers. Chemically, these atomic number 18 proteins. A few rib nucleoprotein enzymes stay been discovered and in some, the catalytic activity lies in the ribonucleic acid part sooner than the protein. These argon known as ribozymes. some(prenominal) catalytic antibodies, abzymes have overly been discovered. Living cells atomic number 18 can-do and a series of physiologic and chemical activities (metabolism) are carried bring out of the closet by them continually for various purposes such(prenominal) as building of naked as a jaybird tissues, successor of old tissues, regeneration of food into chemical energy, brass of fade materials and reproduction for perseveration of life, etc. All such activities (biochemical answers) are carried out by enzymes. J. B. Sumner (1926) uninvolved and crystallized the enzyme urease. Till accompaniment hundreds of enzymes are isolated and characterized. An enzyme binds temporarily to one or to a greater extent substrates / reactants of the re military action it catalyzes. It accelerates the rate of a biochemical reaction by great(p) the activation energy compulsory to carry out the reaction without the enzyme (Without the enzyme the reaction would take puzzle at a rate far too sulky than the pace of metabolism.

Sugar straight off in a container in the kitchen will never rest period down into nose candy dioxide and piddle, if it is stored at the room temperature. It breaks down into carbon dioxide and water supply by reacting with the atmospherical oxygen, only when we burn or oxidize it. But in the consistence, it is oxidized into carbon dioxide and water by the action of a series of enzymes at the body temperature. In this process, it releases energy, which is used by the body. Same is the case for chute-the-chute acids and proteins. Extreme pH, high temperature and opposite chemical conditions are needed to oxidize oleaginous acids and proteins in a test tube. In the living cells, however, the oxidation of fatty acids and proteins is achieved at physiological pH and body temperature by the action of a series of enzymes.
