In photosynthesis, Rubisco catalyzes two alternative reactions: carboxylation and
oxygenation of RuBP. The carboxylation reaction utilizes CO2 in the chloroplasts,
whereas the oxygenation reaction eventually leads to CO2 production in the
mitochondria. An irregular oscillation of the internal CO2 concentration was observed in
a previously published experimental study in a low CO2 environment [Roussel et al., J.
Plant Physiol. 2007, 164, 1188.], where it was hypothesized that photorespiratory CO2
produced in the mitochondria may diffuse to the chloroplast and give rise to the
oscillations. I built a compartmental model of the process with delay. I analyzed the
model through a graphical analysis method and found that my model has the potential to
oscillate, but only when there are delays. In addition, I found that the model displays both
the regular and irregular oscillations at different parameter sets, but at unrealistic
parameter values leading to unrealistic CO2 concentrations.
