1.Aerobic cellular respiration: In the absence of oxygen â what processes stop? Why do they stop?
2. Do the reactions that are unique to fermentation itself (not the reactions of glycolysis that precede the fermentation-specific steps) provide the cell with additional useful high-energy molecules? Explain briefly. If you answered yes â how many high-energy molecules and what kind? If you answered no â then why does the cell do the fermentation step?
3. Do the cells in your body do fermentation? Explain.
4. When cells use fermentation instead of aerobic cellular respiration, is NAD+/NADH involved in this process? What happens to this molecule? Explain briefly.
5. Your body can harness energy from sources besides carbohydrates like glucose. Briefly explain how proteins and fats can be broken down and funneled into the reactions of cellular respiration.
