Enzymes and Metabolic Rates

Introduction Enzymes are catalysts that speed up chemical reactions without being consumed or changed themselves. Each enzyme has a substrate that will match perfectly, almost as if it is a lock and key fit. If the substrate does not fit the enzyme only partial to no function will occur. Each enzyme is formed of polypeptide chains that wind and bend to form complex grooves and valleys. These grooves are the active sites. The active site is where the substrate will fit perfectly. Certain things can change or denature, or breakdown, an enzyme. Some of these factors include variations of pH levels, temperature, and the presence of inhibitors. These factors can be detrimental to an enzyme and cause it to become denatured. Enzymes have to stay in a stable “environment” with the correct “climate” in order to function correctly. When the pH becomes too acidic or too basic the enzyme will begin to breakdown and no longer be able to function correctly. The same concept is held with temperature, when the temperature becomes too hot or too cold the enzyme will denature. These are both testable with the experiment at hand. The purpose of this experiment is to test how enzymes react in certain conditions such as, the effect of temperature and pH. When conducting these experiments the effect of these factors will be seen and easily studied. The data collected will be useful in providing additional visual tools. The hypothesis being tested is; if the pH…
