Lecture 7A – Cellular Respiration 1. Write the summary equation for cellular respiration. 2. In general terms, explain the role of the electron transport chain in cellular respiration. 3. Describe where pyruvate is oxidized to acetyl CoA, what molecules are produced, and how this process links glycolysis to the citric acid cycle. 4. List the products of the citric acid cycle. Explain why it is called a cycle. 5. Distinguish between substrate-level phosphorylation and oxidative phosphorylation. 6. In general terms, explain how the exergonic “slide” of electrons down the electron transport chain is coupled to the endergonic production of ATP by

Unformatted text preview: chemiosmosis. 7. Explain where and how the respiratory electron transport chain generates a proton gradient. 8. Summarize the net ATP yield from the oxidation of a glucose molecule by constructing an ATP ledger. 9. Explain why it is not possible to state an exact number of ATP molecules generated by the oxidation of glucose. 10. Compare the fate of pyruvate in alcohol fermentation and in lactic acid fermentation. 11. Compare the processes of fermentation and cellular respiration.
