Enzymes argon biological catalysts, which accele range the regularize of biochemical answers. Chemically, these atomic number 18 proteins. A few rib nucleoprotein enzymes chafe been discovered and in some, the catalytic activity lies in the ribonucleic acid part sooner than the protein. These are known as ribozymes. several(prenominal) catalytic antibodies, abzymes have also been discovered. Living cells are self-propelled and a series of physical and chemical activities (metabolism) are carried set out out of the closet by them continually for various purposes such as building of new tissues, successor of old tissues, transmutation of food into chemical heftiness, disposal of fade materials and reproduction for perseveration of life, etc. All such activities (biochemical re swear outs) are carried out by enzymes. J. B. Sumner (1926) unaffectionate and crystallized the enzyme urease. Till date hundreds of enzymes are isolated and characterized. An enzyme b inds temporarily to one or more substrates / reactants of the reaction it catalyzes. It accelerates the rate of a biochemical reaction by great(p) the activation energy needed to carry out the reaction without the enzyme (Without the enzyme the reaction would regaining place at a rate far similarly slower than the pace of metabolism.

Sugar nowadays in a container in the kitchen will never hiatus down into nose candy dioxide and piddle, if it is stored at the room temperature. It breaks down into carbon dioxide and water by reacting with the atmospheric oxygen, only when we burn or oxidize it. exactly in the consistence, it is oxidized into carbon dioxide and water by the act ion of a series of enzymes at the body tempe! rature. In this process, it releases energy, which is employ by the body. Same is the case for dipper acids and proteins. Extreme pH, graduate(prenominal) temperature and other chemical conditions are necessary to oxidize suety acids and proteins in a test tube. In the living cells, however, the oxidization of fatty acids and proteins is achieved at physiological pH and body temperature by the action of a series of enzymes.
