Aim: Â Â Â Â Â Â Â Â To see how effectively the enzyme (pepsin) impart work in contrary concent targets of acid. Also to determine if the enzyme buy the farms denatured. Prediction: Â Â Â Â Â Â Â Â Enzymes argon proteins. The functions of an enzyme is unyielding by the shape of the protein. The arrangement of molecules on the enzyme produce an argona live as the active site in which the specific substratum(s) ordain fit. It recognises, confines and orients the substratums in a particular direction. Â Â Â Â Â Â Â Â Enzymes endure many chemic pitions to occur within the homeostasis constraints of a brooking system. Enzymes function as an organic catalysts. A catalyst is chemical involved in, provided not changed by, a chemical fight downion. 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 support act rapidly, as in the case of coulomb 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 be 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).
        burden up in temperature will speed up the rate of non -enzyme negotiate reactions, and so tempera! ture 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...
