lesson 10 Flashcards
photosynthesis
6 CO2 + 12 H2O + light -> C6H12O6 + 6H2O + 6O2
chloroplasts and mitochondria form an energy cycle
photosynthesis uses products of respiration as starting substrate
vise versa
light depdentent reactions
-require light
-occcur in the thylakoid
-capture energy from sunlight
-make ATP and reduce NADP+ to NADPH
-produce O2 as a by product
light independent reactions (carbon fixation)
does not require light
occur in the stroma
use ATP and NADPH to synthesize organic molecules from CO2
ATP is produced via Chemiosmosis
ATP synthase uses proton gradient to provide energy for ATP synthesis
light independent reactions (calvin cycle)
carbon fixation:
uses ATP as enrgysource
uses NADPH as source of protons and electrons
converts inorganic CO2 into organic carbphydrates
calvin cycle
1.carbon fixation:
RuBP + Co2-> 2 PGA
uses rubisco
2. reduction:
PGA is reduced to G3P
3. regeneration of RuBP
G3P used to regenerate RuBP
3 turns to produce new G3P
6 turns for 1 glucose molecule
