1. Explain; a) What is the role of oxygen in the aerobic respiratory pathways and b) What would
happen if oxygen is not present in the process.
2. What is the NAD? Explain how it carries out its function
3. Describe the structure and function of the mitochondria
4. Write the chemical formula for aerobic cell respiration
5. List the 4 pathways that constitute cell respiration
6. We know that Glucose has a Delta G of -686 kilocalories per mol. During glycolysis only a
fraction of this energy is realized into ATP and NADH (ATP = -7.3 and NADH = -53
kilocalories per mol). Where is the rest of the energy at the end of glycolysis?
7. Where does the CO2 that we exhale comes from?
8. Indicate the molecules that inhibit and activate the phosphofructokinase (fig. 9.20)
9. For each of the 4 pathways, indicate the entry molecule, the exit molecule, ATP production,
and NADH production. You may make a table
