  1. What is the next aerobic pathway following the formation of acetyl coenzyme A?
    Citric Acid Cycle (Krebs Cycle)
  2. Is oxygen required in the citric acid cycle?
    Yes, but it is not consumed
  3. Is the citric acid cycle aerobic or anaerobic?
    aerobic
  4. Where does the citric acid cycle occur?
    In the mitochondria
  5. What serves as fuel to drive the citric acid cycle?
    acetyl coenzyme A
  6. What byproduct is acetyl coenzyme A decomposed to in the citric acid cycle?
    CO2
  7. What is the beneficial product of the citric acid cycle?
    • NADH
    • FADH2
  8. What is the first step of the citric acid cycle?
    formation of citric acid from acetyl coenzyme A
  9. What catalyzes each step of the citric acid cycle?
    enzymes
  10. During the citric acid cycle, how many rotations occur for each glucose molecule?
    2
  11. Why are there 2 rotations of the citric acid cycle for each glucose molecule?
    because there are 2 acetyl coenzyme A's
  12. How many different end products are generated by the citric acid cycle? Name them
    • 4
    • CO2
    • ATP
    • NADH
    • FADH2
  13. How many of each product of the citric acid cycle are produced?
    • 4 CO2
    • 2 ATP
    • 6 NADH
    • 2 FADH2
  14. What is the waste product of the citric acid cycle?
    4 CO2
  15. What leaves the citric acid cycle to enter and serve as fuel for the electron transport chain?
    NADH & FADH2
