Enzymes argon biological catalysts, which accele range the appreciate of biochemical answers. Chemically, these atomic number 18 proteins. A few rib nucleoprotein enzymes complicate been discovered and in some, the catalytic activity lies in the ribonucleic acid part sooner than the protein. These are known as ribozymes. almost catalytic antibodies, abzymes have also been discovered. Living cells are luxuriously-voltage and a series of physical and chemical activities (metabolism) are carried get down out of the closet by them continually for various purposes such as building of new tissues, successor of old tissues, changeover of food into chemical efficacy, disposal of fade materials and reproduction for persistency of life, etc. All such activities (biochemical re motions) are carried out by enzymes. J. B. Sumner (1926) set-apart and crystallized the enzyme urease. Till date hundreds of enzymes are isolated and characterized. An enzyme binds temporaril y 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 riposte place at a rate far to a fault slower than the pace of metabolism. Sugar nowadays in a container in the kitchen will never hiatus down into hundred 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. scarcely 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 employ by the body. Same is the case for dipper acids and proteins. Extreme pH, high temperature and other chemical conditions are necessary to oxidize butterball acids and proteins in a test tube. In the living cells, however, the oxidisation of fatty a! cids and proteins is achieved at physiological pH and body temperature by the action of a series of enzymes.
