Aim: Â Â Â Â Â Â Â Â To see how effectively the enzyme (pepsin) impart work in contrary concent swans of acid. Also to determine if the enzyme fashions denatured. Prediction: Â Â Â Â Â Â Â Â Enzymes argon proteins. The functions of an enzyme is obdurate by the shape of the protein. The arrangement of molecules on the enzyme produce an argona eff as the active site in which the specific substratum(s) testament fit. It recognises, confines and orients the substratums in a particular direction. Â Â Â Â Â Â Â Â Enzymes allow in many an(prenominal) chemic pitions to occur within the homeostasis constraints of a forage system. Enzymes function as an organic catalysts. A catalyst is chemical involved in, entirely not changed by, a chemical controvertion. many enzymes function by lowering the activation energy in reactions. By bringing the reactants closer together, chemical bonds may be weaken and reactions will proceed faster than without a catalysts . Â Â Â Â Â Â Â Â Enzymes validate act rapidly, as in the case of ascorbic acid copyic anhydrase, which causes the chemicals to react 107 times faster than without the enzymes present. Carbonic anhydrase speeds up the transfer of carbon dioxide from cells to the blood. There argon over 2000 known enzymes, each of which are involved with one specific chemical reaction. Enzymes are substrate specific. The enzyme peptidase (which breaks peptide bonds in proteins) will not work on starch (which is broke down by human-produced amylase in the mouth).
        summate up in temperature will speed up the rate of non-enzyme negotiate reacti! ons, and so temperature increase speeds up the enzyme mediated reaction, but just to a certain point. When heated too much, enzymes become denatured, because they are proteins dependant on the shape. When/if the temperature drops, the enzyme regains its original shape. Concentration of substrate and point of intersection to a fault controls the rate of the reaction, providing biofeedback mechanism.         Changes in pH will also denature the enzyme, by ever-changing the shape...
