||Abstract: "[Investigators] performed in vivo isotopic labeling of Arabidopsis thaliana rosettes with (13)CO2 and estimated fluxes throughout leaf photosynthetic metabolism by INST-MFA [Isotopically nonstationary metabolic flux analysis]. Plants grown at 200 µmol m^(-2)s^(-1) light were compared with plants acclimated for 9 d at an irradiance of 500 µmol⋅m^(-2)⋅s^(-1)."
||P.16967 left column bottom paragraph: "For 95% of all terrestrial plants (i.e., C3 plants), the reductive pentose phosphate (Calvin–Benson–Bassham, or CBB) cycle directly links light and dark reactions and sustains anabolic activities (ref 5). RuBisCO (ribulose-1,5-bisphosphate carboxylase oxygenase) plays a central role in the cycle by carboxylating ribulose-1,5-bisphosphate (RUBP) with CO2 to form two 3-phosphoglycerate (3PGA) molecules. The other 10 enzymes in the CBB cycle regenerate the RUBP substrate to repeat this process. RuBisCO has a low turnover rate (∼3/s, primary source) and also performs a competitive oxygenation side reaction that limits carboxylation activity."
