photorespiration~Photorespiration involves three organelles: the chloroplast, the peroxisome, and the mitochondria. At conditions of low CO2 concentration and high O2 concentration, ribulose bisphosphate is oxidized to 3-phosphoglycerate and 2-phosphoglycolate. The two-carbon molecule, 2-phosphoglycolate is converted to glycine. The decarboxylation of two glycines generates serine, CO2 and NH3. Serine is further converted to 3-phosphoglycerate. 3-phosphoglycerate generated from photorespiration re-enters the CO2 fixation Calvin cycle. NH3 is re-fixed by glutamine synthetase. The outcome of photorespiration is loss of CO2 and energy in photosynthetic cells. The biological function of photorespiration is not clear. One possibility is that photorespiration is necessary under conditions of high light intensity and low CO2 concentration (i.e. when stomata is closed under water stress) to dissipate excess ATP and reducing power from the photosynthesis light reactions, thus to prevent damage to the photosynthetic apparatus.
