    36 ATP
  2. What is broken down in glycolysis?
  3. The breaking down of glucose in glycolysis results in...
    2 pyruvate
  4. Glycolysis nets...
    2 ATP
  5. In order for glycolysis to occur, ______ is needed as activation energy.
    2 ATP
  6. Glycolysis

    glucose -> 2 _______ -> 2 pyruvate
  7. Gylcolysis occurs in the....
  8. In the absence of oxygen, pyruvate will enter ______________
    anaerobic fermentation
  9. two types of anaerobic fermentation
    alcohol fermentation and lactic acid fermentation
  10. alcohol fermentation produces..
    Carbon dioxide and ethyl alcohol
  11. fermentation is important because it replenishes....
  12. In the presence of oxygen, pyruvate enters...
    aerobic respiration
  13. aerobic respiration occurs in the
  14. The first step of aerobic respiration is the _________________ so the molecule can enter the kreb cycle
    transition step
  15. In the transition step, this enzyme combines with 2 carbons from pyruvate
    co-enzyme A
  16. The molecule created by co enzyme A and 2 carbons from pyruvate is called...
    acetyl coenzyme A
  17. The 6 carbon molecule created as the first step in the Kreb's cycle is called
    citric acid
  18. As citric acid is converted to a 5 carbon molecule, this "comes off" the cycle...
    1 CO2 and 1 NADH is created
  19. What is created/comes off in the Kreb's Cycle as the 5 carbon molecule is changed into a 4 carbon molecule?
    1 CO2, 1 NADH and 1 ATP
  20. As the 4 carbon molecule releases its extra electrons moving up the cycle, these molecules are created
    1 NADH and 1 FADH2
  21. The overall net for the kreb's cycle is:
    • one cycle: 1 ATP, 4 NADH, 1 FADH2
    • one glucose: 2 ATP, 8 NADH, 2 FADH2
  22. The Kreb's cycle occurs in the
  23. high energy molecules that transport electrons to the ETC
    NADH and FADH2
  24. the ETC occurs in the
    cristae or membrane
  25. As NADH and FADH2 donate electrons to ETC this uses the energy to escape to the intermembrane space
  26. the electrons move through a series of _________ in the ETC
  27. at the end of the ETC, the electron is used in the creation of ______
  28. the build up of H+ in the intermembrane space creates a
    concentration gradient
  29. The concentration gradient "pushes" the H+ through this enzyme embedded in the membrane
    ATP synthase
  30. as H+ flows through ATP synthase, it turns....creating_-
  31. This is the ATP net gain of ETC
    32 ATP
  32. The H+ coming back into the matrix join with _________ to make water
    molecular oxygen
  33. overall equation of cellular respiration
    glucose + oxygen -> water + energy + carbon dioxide
