62 PROCEDURE, PART II A student designed an experiment to determine the effect of pH on the action of peroxidase. She took five test tubes, and labeled them A - E. She placed the following in the tubes: Tube A Tube B Tube C Tube D Tube E 2 mL of: PH 2 buffer PH 5 buffer PH 7 buffer pH 9 buffer PH 11 buffer 1 cm of: ground potato ground potato ground potato | ground potato ground potato 2 mL of: hydrogen hydrogen hydrogen hydrogen hydrogen peroxide peroxide peroxide peroxide peroxide The results are seen below: Tube A Tube B Tube C Tube D Tube E Height of 0.5 3.2 2.0 foam (cm): 0 0 Use the sheet of graph paper on page 14 to prepare a line graph of the results. Be sure to put the independent variable on the X axis. ( You may need to review the graphing instructions on pages 9 - 10 of your lab manual.)
