  1. steps in cyclic photophosphorylation: e- flows through __ (List all steps)
    • photosystem I
    • to ferredoxin
    • to plastiquinone
    • to cytochrome
    • to plastocyanin
    • then back to photosystem I

    (page 26 on slide)
  2. Unlike the noncyclic pathway, the cyclic pathway doesn't make __
    NADPH
  3. the pathway of CO2 fixation
    Calvin cycle
  4. In the calvin cycle __ is reduced to __
    CO2; carbs (glucose)

    (CO2 fixation, must take place in light)
  5. calvin cycle: Enzymes in the __ use the energy in __ & __ (from light-dependent reactions) to __ CO2
    stroma; ATP; NADPH; reduce
  6. 3 processes of the calvin cycle
    • 1. carbon fixation
    • 2. reduction & sugar production
    • 3. regeneration of RuBP

    (page 29 on slide)
  7. carbon fixation: __ & __ is at the active site of __
    RuBP (5 carbon molecule) & CO2; rubisco

    (page 30 on slide)
  8. Rubisco creates an unstable __ carbon compound that immediately breaks down into __ molecules of __
    6; 2; 3PG (3 carbon molecules)

    (page 30 on slide)
  9. reduction & sugar production step of calvin cycle
    • 3PG gets e- from NADPH
    • Reduction takes place. (3GP to G3P)
    • Glucose molecules are produced.
  10. __ is the product of the calvin cycle. Most is recycled into __; the rest is used to make __
    G3P; RuBP; sugars (glucose) or stored starch
  11. regeneration of RuBP
    Carbon is used to regenerate RuBP (so it can bind to rubisco) so the cycle can continue to make more glucose
