Chapter 9 – Cellular Respiration: Harvesting Chemical Energy – Homework
1. Write out the basic balanced equation for cellular respiration.
2. In the conversion of glucose and oxygen to carbon dioxide and water, which molecule
is reduced? How do you know? Which molecule is oxidized? How do you know?
3. Make a table showing the three main reactions of cellular respiration.
For each reaction show the following information:
location in the cell, function of the reaction, input or requirements, output or products.
4. Go back to question 1 and your balanced equation. Identify which one of the three
reactions of cellular respiration each part of the equation is from.
(e.g. which reaction has glucose as a requirement?)
5. What is the function of coenzyme A in cellular respiration?
6. Why is the energy investment phase of Glycolysis necessary?
7. What is the role of oxygen in cellular respiration?
8. What is the adaptive value of fermentation? If given a choice, would a yeast cell
“prefer” to conduct fermentation or cellular respiration? Explain.
9. Contrast and compare substrate-level phosphorylation versus oxidative
phosphorylation. Identify which stage of cellular respiration each occurs.
10. Why is Glycolysis considered one of the first metabolic pathways to have evolved?
11. Did the ETC evolved before or after photosynthesis? Explain.
12. Why is the value of 3 ATP/NADH only an approximation?
13. What is the adaptive value of having ATP synthase in the inner membrane instead of
the outer membrane of the mitochondria?
14. The efficiency of respiration is approximately 40%. Where does the rest of the
energy go? Explain.
15. How do you think the mitochondria compare between a fat cell and a liver cell?
Explain.
16. Why is chemiosmosis called a proton-motive force?
