Question 1 (3 points) You are studying enzymes in biology class. Hydrogen peroxide (H2O2) is produced as a byproduct of respiration. Hydrogen peroxide is harmful to cells and must be continually broken down. Catalase is an enzyme found in living cells that speeds up the breakdown of hydrogen peroxide into water and oxygen (2 H2O2 → 2 H2O + O2). You are working with your lab group to investigate what factors influence the rate of the peroxide reaction. Your lab group is provided with liver samples as a source of catalase, as well as 3% hydrogen peroxide. You and your lab partner place 2 g slices of liver into 3 test tubes containing water, vinegar, or baking soda. You add 15 ml of hydrogen peroxide to each and measure the amount of oxygen produced every 30 seconds for 3 minutes. Now that you have completed the experiment, you need to graph your results. You decide to make a triple line graph showing the rate of reaction (oxygen produced/30 sec.) for each of the three solutions. On your graph, where should you put the oxygen production? a on the x axis because it is the dependent variable b on the x axis because it is the independent variable c on the y axis because it is the independent variable d on the y axis because it is the dependent variable
