QUESTIONS
1. What is catabolism? Anabolism? Is cellular respiration anabolic or catabolic?
2. Write the overall formula for aerobic respiration and alcohol fermentation.
3. Summarize the steps in aerobic respiration; listing products and reactants for each
stage and telling where in the cell each stage occurs.
4. Summarize the production of ATP for each of the three stages in aerobic respiration.
5. Explain the role of electron-carrier molecules such as NADP.
6. Explain how the production of ATP(oxidative phosphorylation) occurs according to the
chemiosmotic hypothesis. Use a diagram of a mitochondrion in your explanation.
7. Explain the process of fermentation.
8. Diagram a mitochondrion, show where the Krebs cycle and ETS are found.
9. Outline Mitchell's chemiosmotic hypothesis.
10. What arguments would you use to justify calling the mitochondria the "powerhouse" of
the cell?
11. What is the specific role of oxygen in an aerobic cell?
12. When and where does anaerobic respiration occur in humans? What is the end product
of this anaerobic respiration?
