Photosynthesis Ch. 7 Carbon Fixation
Reactions (C3 Biochemical Reactions)
2
Energy Transduction (Light-Dependent)
Reactions -where? At thylakoid -what? -photoly
sis of water 2H2O ? 4e- 4H O2 -ATP
synthesis (ADP Pi ? ATP) -reduction of NADP
NADP 2e- H ? NADPH
3
Carbon-fixation Reactions -where? in
stroma -what? ATP and NADPH used to fix CO2

Rubisco

Photorespiration The problem with Rubisco
(RuBP carboxylase/oxygenase)
RuBP CO2 ? 2 3-PGA (phosphoglycerate)
(Yeah!!) RuBP O2 ? 1 3-PGA 1
phosphoglycolate (Boooo!!)

The salvage of phosphoglycolate
