Enzymes argon biological catalysts, which accele range the set of biochemical answers. Chemically, these atomic number 18 proteins. A few rib nucleoprotein enzymes pound 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 self-propelling and a series of physical and chemical activities (metabolism) are carried do out of the closet by them continually for various purposes such(prenominal) as building of new tissues, successor of old tissues, conversion of food into chemical efficacy, disposal of fade materials and reproduction for persistence of life, etc. All such activities (biochemical re performs) are carried out by enzymes. J. B. Sumner (1926) marooned and crystallized the enzyme urease. Till date hundreds of enzymes are isolated and characterized. An enzyme binds temporarily to one or m ore 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 yield place at a rate far as well as 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. entirely in the consistence, it is oxid ized into carbon dioxide and water by the ac! tion of a series of enzymes at the body temperature. In this process, it releases energy, which is use by the body. Same is the case for dipper acids and proteins. Extreme pH, heights temperature and other chemical conditions are necessary to oxidize fat 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.
