Glycolysis & Formation of Acetyl CoEnzyme A

  1. What is glucose oxidation called?
    cellular respiration
  2. What is the chief source of the body's energy?
    cellular respiration
  3. Where does cellular respiration occur? In what cells do cellular respiration not occur?
    Almost every cell of the body except red blood cells
  4. Why does cellular respiration not occur in RBCs?
    they lack mitochondria
  5. How many chemical products are derived from the complete oxidation of glucose during cellular respiration? What are the products?
    • 2
    • ATP and H2O
  6. How many stages are typically involved in the complete oxidation of glucose in the body? What are those stages?
    • 4
    • Glycolysis
    • Formation of Acetyl Coenzyme A
    • Citric Acid Cycle (Krebs Cycle)
    • Electron Transport Chain
  7. What is the literal meaning of glycolysis?
    sugar splitting
  8. Where does glycolysis occur?
    in the cytoplasm (outside of the mitochondria)
  9. How many molecules of ATP are produced for each molecule of glucose in glycolysis?
    2 net
  10. Two ATP molecules are required to start glycolysis by reducing 2 molecules of _______ to form 2 molecules of ________.
    • NAD+
    • NADH
  11. How many carbon molecules are found in glucose?
    6
  12. In glycolysis, what is a glucose molecule split into?
    2 molecules of pyruvic acid
  13. How many carbon atoms are contained in a pyruvic acid molecule?
    3
  14. Is glycolysis aerobic or anaerobic?
    anaerobic
  15. After pyruvic acid is produced, how many routes may if follow? What are those routes?
    • 2
    • pyruvic acid moves into the mitochondria >Formation of acetyl coenzyme A (aerobic)
    • pyruvic acid remains outside the mitochondria and is consumed in the production of small amounts of ATP (anaerobic)
  16. What is the byproduct of anaerobic metabolism?
    lactic acid
  17. How much ATP is produced under anaerobic conditions?
    4 total (2) net
  18. Following glycolysis, what is the next aerobic pathway?
    Formation of Acetyl Coenzyme A
  19. In the formation of acetyl coenzyme A, what is pyruvic acid converted into?
    an acetyl group (2 carbons)
  20. what molecule combines with the acetyl group inside the mitochondria?
    Coenzyme A
  21. How many pyruvate molecules are converted to acetyl coenzyme A for each glucose molecule?
    2
  22. How many acetyl coenzyme A molecules are produced for each glucose molecule?
    2
  23. During the formation of Acetyl Coenzyme A from a single glucose molecule, how many molecules of NAD+ are involved?
    2
  24. What are the 2 molecules of NAD+ reduced to in forming acetyl coenzyme A?
    2 NADH
  25. What is the byproduct in the formation of acetyl coenzyme A?
    2 molecules of CO2
  26. How many molecules of CO2 are citric acid cycle byproducts?
    4 CO2
  27. Is oxygen required in the formation of acetyl coenzyme A?
    Yes, but it isn't consumed.
  28. Is the formation of acetyl coenzyme A considered aerobic or anaerobic?
    aerobic
  29. Following the formation of acetyl coenzyme A, what is the next aerobic pathway?
    Citric Acid Cycle
