Study Guide – Chapter 9 Cellular Respiration

1. In redox reactions how are oxidation and reduction linked? 2. How does redox chemistry related to the function of NAD and FAD in cells? 3. How does substrate level phosphorylation get its name? 4. Why is there a difference in the gross production of ATP by glycolysis and the net

production of ATP by glycolysis? 5. How does pyruvate dehydrogenase connect glycolysis and the citric acid cycle? 6. Why is the citric acid cycle called a cycle? 7. What is the role of the electron transport chain in oxidative phosphorylation? 8. Explain why the matrix has a higher pH than the cytosol? 9. Explain how chemiosmosis generates ATP? 10. Account for the ATP produced by cellular respiration from the catabolism of one

glucose molecule? 11. The ultimate fate of the electrons from glucose in cellular respiration is to form

water from oxygen. In what sense is the ultimate source of electrons in glucose from water?

12. Of the three parts of cellular respiration, what processes are involved in the catabolism of fatty acids to form ATP?

13. Pyruvate dehydrogenase is inhibited by high levels of NADH. How does this regulation benefit cells?

14. Phosphofructokinase is inhibited by citrate. How does this regulation benefit cells?

15. Lactate dehydrogenase produces lactate from pyruvate during fermentation. How does this process benefit cells?
