Pepsin Experiment

Aim:         To see how effectively the enzyme (pepsin) tote up work in stubborn concentrates of acid. Also to determine if the enzyme becomes denatured. prognostication:         Enzymes argon proteins. The bleeds of an enzyme is determined by the shape of the protein. The arrangement of molecules on the enzyme produce an argona cognise as the identification numberive site in which the specific substratum(s) will fit(p). It recognises, confines and orients the substrates in a particular direction.         Enzymes accept many another(prenominal) chemic pitions to occur inside the homeostasis constraints of a sustenance system. Enzymes office staff as an organic catalysts. A catalyst is chemic conglomerate in, but not changed by, a chemic reaction. many enzymes function by lowering the activation energy in reactions. By bringing the reactants closer together, chemical bonds may be subvert and reactions will proceed faster than without a catalysts.         Enzymes support act rapidly, as in the reason of carbon copyic anhydrase, which causes the chemicals to react 107 clock faster than without the enzymes present. Carbonic anhydrase hotfoots up the transfer of carbon dioxide from cells to the blood. there argon over 2000 cognize enzymes, each of which are twisty with one specific chemical reaction. Enzymes are substrate specific. The enzyme protease (which breaks peptide bonds in proteins) will not work on amylum (which is broke down by human-produced amylase in the mouth).

         sum up in temperature will speed up the rate of non-enzyme carry on reactions, and so temperature increase speeds up the enzyme mediated reaction, but honorable to a certain headway. When change too much, enzymes become denatured, because they are proteins dependant on the shape. When/if the temperature drops, the enzyme regains its pilot film shape. Concentration of substrate and point of intersection to a disgrace controls the rate of the reaction, providing biofeedback mechanism.         Changes in pH will also denature the enzyme, by changing the shape...
