How does the Concentration of the Substrate affect the rate of reaction of the Enzyme Catalase Aim: To find out how the concentration of the substrate affect the rate of reaction of the enzyme catalase. Research Catalase and Hydrogen (Source - Complete Biology text book, Pickering) What is Catalase? Enzymes are very large and complex organic molecules that are synthesized by the cell to perform very specific functions. These biological catalysts are important because they speed up the rate of the reaction they catalyze that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants, animals and aerobic (oxygen requiring) bacteria. It promotes the conversion of hydrogen peroxide, a powerful and potentially harmful oxidizing agent, to water and molecular oxygen. 2H2O2 to 2H2O + O2 Catalase also uses hydrogen peroxide to oxidize toxins including phenols, formic acid, formaldehyde and alcohols. H2O2 + RH2 to 2H2O + R What factors affect the...
