6100411383Light dependent reactionsUse light directly to produce ATP in the grana (1) Light is absorbed by PS II (2) Photolysis (release O2 and provide electron) (3) Photophosphorylation: Electrons flow through ETC and produce ATP (4) Light is absorbed by PS I (5) NADP+ reduced to NADPH using 2nd ETC Reactants: Light and H2O Products: NADPH, ATP, O2 (released)1

6100411387Light independent reactions(Dark reactions, Calvin Cycle) Produce sugar using the Calvin cycle5
6100411388Calvin CycleUses ATP and NADPH from light dependent reactions to fix carbon dioxide into G3P (sugar building block) (1) Fixation: CO2 combines with RuBP to produce carbon chain molecules (2) Reduction: carbon chain molecule reduced into G3P using ATP and NADPH (3) Regeneration: regeneration of RuBP for future carbon fixation Occurs in the stroma6

6100411394PhotorespirationDead-end process where O2 binds to rubisco instead of CO2 in Calvin cycles; does not create sugar or ATP Vestige from ancient Earth, when the atmosphere contained no oxygen to compete with CO212
