Photosynthesis part 2

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)
Unlike the noncyclic pathway, the cyclic pathway doesn't make __

NADPH
the pathway of CO2 fixation

Calvin cycle
In the calvin cycle __ is reduced to __

CO2; carbs (glucose)

(CO2 fixation, must take place in light)
calvin cycle: Enzymes in the __ use the energy in __ & __ (from light-dependent reactions) to __ CO2

stroma; ATP; NADPH; reduce
3 processes of the calvin cycle
- 1. carbon fixation
- 2. reduction & sugar production
- 3. regeneration of RuBP
(page 29 on slide)
carbon fixation: __ & __ is at the active site of __

RuBP (5 carbon molecule) & CO2; rubisco

(page 30 on slide)
Rubisco creates an unstable __ carbon compound that immediately breaks down into __ molecules of __

6; 2; 3PG (3 carbon molecules)

(page 30 on slide)
reduction & sugar production step of calvin cycle
- 3PG gets e- from NADPH
- Reduction takes place. (3GP to G3P)
- Glucose molecules are produced.
__ is the product of the calvin cycle. Most is recycled into __; the rest is used to make __

G3P; RuBP; sugars (glucose) or stored starch
regeneration of RuBP

Carbon is used to regenerate RuBP (so it can bind to rubisco) so the cycle can continue to make more glucose
