1. Write the equation for the fermentation of glucose by yeast:
2. Calculate the rate of carbon dioxide production per minute for each substrate in group 1’s results:
3. A second group of students performed the same experiment. Their results are summarized in the second table. Calculate the rate of carbon dioxide production per minute for each substrate in group 2’s results:
4. What assumptions are being made in this experimental design with the temperature and the pH and do you think they were reasonable?
5. Using the spreadsheet, make the two tables match the IB standards. Put an image of your two tables here.
6. Make a bar graph with the information from questions 2 and 3 and put an image of your graph below.
7. Summarize the results of group 1 ‘s fermentation experiment:
8. Explain the findings based on your understanding of cell respiration and carbohydrate chemistry:
9. Compare the results of the two groups:
10. Provide a probable explanation for any differences in the results:
11. Discuss how you could improve this experiment.
