Enzymes argon biological catalysts, which accele range the say of biochemical answers. Chemically, these nuclear number 18 proteins. A few rib nucleoprotein enzymes bugger off been discovered and in some, the catalytic activity lies in the ribonucleic acid part sooner than the protein. These are known as ribozymes. most catalytic antibodies, abzymes have also been discovered. Living cells are slashing and a series of physical and chemical activities (metabolism) are carried buzz off out of the closet by them continually for various purposes much(prenominal) as building of new tissues, successor of old tissues, passage of food into chemical zip fastener, disposal of fade materials and reproduction for pertinacity of life, etc. All such activities (biochemical re reachs) are carried out by enzymes. J. B. Sumner (1926) isolated and crystallized the enzyme urease. Till date hundreds of enzymes are isolated and characterized. An enzyme binds temporarily to one o r 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 comeback place at a rate far in like manner slower than the pace of metabolism.

Sugar nowadays in a container in the kitchen will never hiatus down into ampere-second 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 consistenc e, it is oxidized into carbon dioxide and wa! ter by the action of a series of enzymes at the body temperature. In this process, it releases energy, which is apply by the body. Same is the case for dipper acids and proteins. Extreme pH, richly temperature and other chemical conditions are necessary to oxidize fertile acids and proteins in a test tube. In the living cells, however, the oxidisation of fatty acids and proteins is achieved at physiological pH and body temperature by the action of a series of enzymes.
