    • description ""
    • Source of chemical energy
    • ATP
  1. Reducing agent
    NADPH
  2. 3 phases
    1-carbon fixation, 2-reduction, 3-regeneration
  3. What is carbon fixation?
    Incorperation of CO2 into organic molecules (hydrocarbons)
  4. Carbon fixation is catalysed by...
    Rubisco (enzyme)- 1 6-C sugar breaks down into 2 phosphoglycerates (PGAs)
  5. What is reduction?
    Where NADPH and ATP from light reactions are used (6 ATP and 6 NADPH)
  6. What is regenerated?
    Starting material- ribulose biphosphate (RuBP) *requires 3 ATP
  7. Need:
    3 CO2, 6 NADPH, 9 ATP
  8. Get:
    1 PGAL, 9 ADP, 9 Pi, 6 NADP
  9. 1 glucose = ?
    2 PGAL
  10. How many times does the cycle go to make 1 PGAL?
    3 (6 for a glucose)
  11. Why PGAL?
    More potential and chemical energy
