Kevin McAllister To examine the effect of Substrate Concentration (Hydrogen Peroxide) on the rate of an enzyme catalysed reaction The reaction we will study is: 2H2O2 ? O2 + H2O Catalase Enzymes are globular proteins with a complex tertiary structure. Weak chemical bonds between the polypeptide chains maintain the shape of the enzyme, which is critical to its function. Each enzyme has a specifically shaped active site. Substrate molecules which have the same shape as the active site may combine with this active centre - forming an enzyme substrate complex. The enzyme and substrate molecules interact in such a way that a chemical reaction occurs and appropriate products are produced. This sequence of events can be repeated very rapidly. Catalase is a good example, it occurs naturally in the body tissues of plants and animals and catalyses the decomposition of Hydrogen peroxide to oxygen gas and water by up to 10,000 times. Substrate Concentration has...
