  1. GLYCOLYSIS INPUTS AND OUTPUTS
  2. GLYCOLYSIS
    KREBS CYCLE
    ETS

    WHICH ONE IS CO2 GIVEN OFF?
    KREBS CYCLE 

  3. GLYCOLYSIS
    KREBS CYCLE
    ETS

    H20 FORMED WHICH ONE?
    ETS.

    OCCURS IN THE MATRIX OF THE MITOCONDRIA.

  4. GLYCOLYSIS
    KREBS CYCLE
    ETS

    WHERE DOES NADH BECOME NAD+
    ETS.

    • OCCURS IN THE MATRIX OF THE MITOCONDRIA.
  5. WHAT THE HELL DOES OXIDATIVE PHOSPHORLYLATON MEAN? WHAT IT IS?
    REFERS TO THE PRODUCTION OF ATP AS A RESULT OF ENERGY RELEASED BY THE ETS.
    • 1. CRISTAE (ETS)
    • 2. OUTER MEMBRANE
    • 3. INNER MEMBRANE SPACE
    • 4. MATRIX (KREBS)

    FYO GLYCOLSIS OCCURS IN THE CYTOSOL.
  6. KREB CYCLE INPUT AND OUTPUT
  7. DEFINE SUBSTRATE LEVEL PHOSPHORYLATION.
    • PER GLUCOSE MOLECULE, THERE IS A NET GAIN OF:
    • 2 ATP FROM GLYCOLYSIS (IN CYTOSOL) AND
    • 2 ATP FROM THE KREB CYCLE  (IN THE MATRIX OF THE MITCHONDRIA.)

    ALTOGETHER 4 ATP FORM OUTSIDE OF THE ETS. (WHICH OCCURS IN THE CRISTAE)
  8. INPUT AND OUTPUT OF FERMENTATION.
  9. OXIDATIVE PHOSPHORYLATION OCCURS WHERE?
    ETS. 

    • MOST ATP IS PRODUCED THIS WAY.
    • (32 OR 34)
  10. CELLULAR RESPIRATION GRAND TOTAL OF ATP PRODUCTION?
    36 OR 38. THE DELIEVERY OF NADH GENERATED OUTSIDE OF THE MITOCHONDRIA EXPLAINS THE DIFFERENCE. IF THE ELECTRON FROM THE NADH ARE DELIEVERED BY A SHUTTLE MECHANISM AT THE START OF ETS, 6 ATP RESULT PER NADH, OTHERWISE 4.
  11. where does the calvin cycle occur?
    STOMA
  12. what does the calvin cycle use?

    NADPH and ATP (from light reactions) to synthesize sugars
  13. what does the calvin cycle require?



     

     oxygen

  14. how many CO2 molecules are used to make PGAL?

    3
  15. how many molecules of PGAL equal a glucose?

    2
  16. how much more energy is stored in glucose than ATP?

    90 TIMES
  17. how many turns of the calvin cycle makes 1 PGAL?

    3
  18. what does the calvin cycle produce?

    ADP and NADP+
  19. DEFINE C4

    -fix carbon in a 4 carbon molecule (PEP)
    -lose less water
    -ex. corn, sugar cane, crabgrass
  20. DEFINE CAM plants

    -open stomata at night and close them during the day
    -fix carbon at night
    -calvin cycle during the day
    -ex. pineapples and cacti
  21. DO CHOLORPLAST HAVE 2 LIPID BILAYERS?
    YES
  22. WHERE DOES PS 1 AND PS 2 OCCUR?
    BOTH IN THYLAKOID. PS 2 THEN PS1.
  23. photosystem 2 contains what pigment?

    chlorophyll a
  24. photosystem 1 contains what pigment?

    chlorophyll b
  25. DEFINE PS2
    sunlight excites electrons in P2
    electrons from chlorophyll are passed to primary electron acceptor
    primary electron acceptor passes electrons to ETC
    it splits a water molecule and steals electrons from it

    oxygen is produced!
  26. high H+ concentration gradiant in where?

    inside the thylakoid (lumen)
  27. Low H+ concentration gradiant in where?

    STOMA
  28. DEFINE PS1
    excited electrons go to ETC 

    electrons from P2 replace electrons lost at P1
  29. ETC + photosynthesis BOTH OCCUR WHERE?

    thylakoid membrane
  30. 2 kinds of mesophyll

    palisade (longer) and spongy (more circular)
    cells where photosynthesis occurs
  31. How many total NADH + H+ go to the electron transport chain?

    10
  32. How many ATP are produced as electrons from each NADH + H+ go through the electron transport chain?

    3
  33. How many total ATP are generated by all the NADH + H+ carried electrons that go through the electron transport chain?

    30
  34. How many FADH2 go through the electron transport chain?

    2
  35. How many total ATP are produced by FADH2 carried electrons going through the electron transport chain in pairs?

    4
  36. Assuming that 2 ATP molecules are used up getting the NADH to the mitochondria, what is the grand total of ATP molecules produced in aerobic cellular respiration of one molecule of glucose?

    36
  37. How many CO2 molecules are produced in the breakdown of one glucose molecule?

    6
  38. How many total pairs of electrons are passed through the electron transport chain?

    12
  39. what are the two layers of plant that contain chloroplasts?

    palisade and spongy layer
  40. outer layer of the vein

    bundle sheath cells
  41. describe what causes the stomata to open

    HIGH WATER PRESSURE
  42. What is the final electron acceptor for the ETC?

    OXYGEN
  43. Where in the mitochondrion does the ETC take place in cellular respiration?

    INNER MEMBRANE
  44. For glycolysis and entire Krebs cycle, you get:

    10 NADH
    2 FADH2
    4 ATP
