Each lab was assigned to a group A, B, C and D in our class performed this experiment. The data presented in this report will reflect the average rates of change in O2 ml/min of our class results. In the later discussion sections, it will become …show more content…
This group loaded the reaction chamber with 4 extract soaked disks. They used 3% H2O2 with a pH of 3 and then ran experiment they recorded their data in Table 3.
d. Then they repeated the experiment using 3% H2O2 with a pH of 5 and recorded the results in Table 3
e. Then they repeated the experiment using 3% H2O2 with a pH of 7 and recorded the results in Table 3
f. Then they repeated the experiment using 3% H2O2 with a pH of 9 and recorded the results in Table 3
g. Then they repeated the experiment using 3% H2O2 with a pH of 11 and recorded the results in Table 3
3. Cleaned up and Washed their hands
4. Recorded and calculated the rate of reaction per minute (see Table 3)
5. Created a line graph to show their data (see Graph 3)
6. Analyzed their data and created a written overview of the results (see results for procedure C)
Group D procedure: The influence of Temperature on Catalase Activity
1. Prepared filter disks
a. Collected and mixed liver extract
b. They put 4 ml of the extract in a test tube and placed it in boiling water for five minutes. Then they put the boiled extract into a petri dish and soaked 4 disks in it
c. Then they pour the rest of the liver extract into a small petri
