Abstract
Atmospheric oxygen is a potent inhibitor of photosynthesis in plants utilizing the C3 pathway. This inhibition is mediated by ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco), in that CO2 and O2 are mutually competitive substrates on the enzyme for RuBP. Oxygenation of RuBP yields glycolate-P, which is subsequently metabolized to CO2 and PGA in photorespiration. The interaction between photosynthesis and photorespiration is determined by the kinetic constants of Rubisco and the chloroplast CO2 and O2 concentrations as described in Eq. 1 (Laing et al. 1974)
