Abstract
The computational analysis of the model system consisting of the processes of CO2 assimilation and photorespiration shows the appearance of sustained oscillations in the system which might reflect their presence in photosynthesizing cells. Concentrations of CO2 and O2 oscillate in opposite phases causing Rubisco switching continuously between the carboxylase (CO2 assimilation) and the oxygenase (photorespiration) reactions. The results of modeling are consistent with carbon isotopic and other observed data. They show that the oscillation period varies from about 1Â s to 3Â s depending on the values of parameters taken. Too high concentrations of O2 suppress the oscillations.
