Report
Catalase Enzymes Concentration Nikole Gaudry Purpose Results Analysis Procedures The purpose of this experiment was to observe enzymes and their reaction with catalase. We observed this by doing multiple experiments with concentration, pH, specificity, and temperature. For this report we will only look at the concentration, Enzymes are biological molecules that speed up the rate of all chemical reactions that take place within a cell. When the enzyme concentration is higher, the reaction rate increases. In this experiment we used Catalase as the enzyme concentration. The hypothesis for this experiment was the enzyme Catalase will increase the rate of oxygen bubbles as the concentration of the enzyme is increased. • Chemicals used: hydrogen peroxide and catalase • This experiment was done 4 different ways: specificity, concentration, temperature, and pH. However, We are only doing concentration • Tube 1: 0.5 cm catalase & 2.5 cm hydrogen peroxide • Tube 2: 1 cm catalase & 3 cm hydrogen peroxide • Tube 3: 1.5 cm catalase & 3.5 hydrogen peroxide After conducting the experiment, on whether or not the rate of bubbles would increase when mixed with a higher concentration of Catalase and hydrogen peroxide. The results supported our hypothesis. As shown in the graph, the higher the concentration of the Catalase enzyme the more oxygen bubble formed. This shows that once the enzyme concentration is increased, so does the rate and amount of oxygen bubbles produce. As when the concentration was lower no bubble formed or the rate was slower. Therefore, catalase with react faster, causing oxygen bubbles to form, when the concentration is increased. 0.5 Cat 1.0 Cat 1.5 Cat Tube 1 Tube 2 Tube 3 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0 0.7 0.8 Group Bubble Height Formed
