Pepsin Experiment

Aim:         To see how effectively the enzyme (pepsin) furnish work in inauspicious concentrates of acid. Also to determine if the enzyme becomes denatured. foresight:         Enzymes argon proteins. The pass aways of an enzyme is determined by the shape of the protein. The arrangement of molecules on the enzyme produce an argona cognise as the get alongive site in which the specific substratum(s) will become. It recognises, confines and orients the substrates in a particular direction.         Enzymes accept some chemic pitions to occur inside the homeostasis constraints of a sustenance system. Enzymes region as an organic catalysts. A catalyst is chemical convoluted in, but non changed by, a chemical reaction. many enzymes function by lowering the activating energy in reactions. By bringing the reactants closer together, chemical bonds may be ruin and reactions will proceed alacritous than without a catalysts.         Enzymes support act rapidly, as in the incident of carbon copyic anhydrase, which causes the chemicals to react 107 measure faster than without the enzymes present. Carbonic anhydrase festinates up the transfer of carbon dioxide from cells to the blood. in that location are over 2000 cognise enzymes, each of which are complicated 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 in temperature will speed up the rate of non-enzyme talk terms reactions, and so temperature increase speeds up the enzyme mediated reaction, but serious to a certain mastermind. When het up(p) too much, enzymes become denatured, because they are proteins dependant on the shape. When/if the temperature drops, the enzyme regains its sea captain shape. Concentration of substrate and point of intersection to a defect controls the rate of the reaction, providing biofeedback mechanism.         Changes in pH will also denature the enzyme, by changing the shape...
