Aim: Â Â Â Â Â Â Â Â To see how effectively the enzyme (pepsin) impart work in contrary concent puts of acid. Also to determine if the enzyme beats denatured. Prediction: Â Â Â Â Â Â Â Â Enzymes argon proteins. The functions of an enzyme is rigid by the shape of the protein. The arrangement of molecules on the enzyme produce an argona cognize as the active site in which the specific substratum(s) give fit. It recognises, confines and orients the substratums in a particular direction. Â Â Â Â Â Â Â Â Enzymes film umpteen chemic pitions to occur within the homeostasis constraints of a musical accompaniment system. Enzymes function as an organic catalysts. A catalyst is chemic involved in, precisely not changed by, a chemical pition. 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 substitute act rapidly, as in the case of deoxycytidine monophosphate 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 are 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).
        sum up up in temperature will speed up the rate of non-enzyme negotiate reactions! , 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 changing the shape...
