Cellular Respiration


Objectives:

  1. Diagram energy flow through the biosphere
  2. Describe the overall summary equation for cellular respiration
  3. Distinguish between substrate-level phosphorylation and oxidative phosphorylation
  4. Explain how exergonic oxidation of glucose is coupled to endergonic synthesis of ATP
  5. Define oxidation and reduction
  6. Explain how redox reactions are involved in energy exchanges
  7. Define coenzyme and list those involved in respiration
  8. Describe the structure of coenzymes and explain how they function in redox reactions
  9. Describe the role of ATP in coupled reactions
  10. Explain why ATP is required for the preparatory steps of glycolysis
  11. Describe how the carbon skeleton of glucose changes as it proceeds through glycolysis
  12. Identify where in glycolysis the sugar association, substrate-level phosphorylation, and reduction of coenzymes occur
  13. Write a summary equation for glycolysis and describe where it occurs in the cell
  14. Describe where pyruvate is oxidized to acetyl CoA, what molecules are produced, and how pyruvate links glycolysis to the Krebs cycle
  15. Explain at what point during cellular respiration complete oxidation of glucose occurs
  16. Explain how the exergonic "slide" of electrons down the electron transport chain is coupled to the endergonic production of ATP by chemiosmosis
  17. Describe the process of chemiosmosis
  18. Explain how membrane structure is related to membrane function in chemiosmosis
  19. Describe the fate of pyruvate in the absence of oxygen
  20. Explain why fermentation is necessary
  21. Distinguish between aerobic and anaerobic metabolism
  22. Describe how food molecules other than glucose can be oxidized to make ATP
