Photorespiration begins in the chloroplast, when rubisco attaches to RuBP in its oxygenase reaction. A comprehensive analysis of free-air CO 2 enrichment experiments unambiguously demonstrated that increasing photosynthesis in C 3 plants increases yield (Ainsworth and Long, 2005).In C 3 photosynthesis, Rubisco (ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase . catalyses carboxylation and oxygenation. RUBISCO activase can reactivate a site by removing RuBP and carbamylating the site. With longer exposures, some of the 3- PGA became labeled with TWO 14C, indicating that some PGA was being recycled and having a radioactive 14CO2 being added to it, when it already had a 14C from an earlier fixation reaction.
