Charlotte Eaddy Enzyme Lab Report June 3, 2021
Introduction Enzymes are catalysts that help increase reaction rate by lowering the minimum amount of energy that is required to start a chemical reaction. The two types of enzymes are catabolic or anabolic. Catabolic releases energy and anabolic uses energy. Enzymes are commonly used in our metabolism. Metabolism is the process of how the human body utilized chemical reactions to conform food into energy, and enzymes aid in that process by each enzyme working with specific reactions. Substrates are shaped differently in order for each enzyme to bind to that specific substrate. Temperature, pH, concentration, and chemicals binding to an enzyme are the various factors that affect the reaction rate. The first experiment is how the protein catalase, a common enzyme in animals, plants, and microorganisms, affects the substrate hydrogen peroxide. Since catalase can decompose hydrogen peroxide, it is hypothesized that the higher the concentration of catalase the higher the reaction rate time. The second experiment is how the temperature of hydrogen peroxide affects the decomposition rate with catalase. Since high temperature increases enzyme reaction, it is hypothesized that the higher the temperature the longer the reaction rate.
