Photosynthesis Thermodynamic Efficiency Facing Climate Change
Abstract
A mathematical model that describes the oscillatory dynamic experimentally observed in the volumetric flows of CO2/O2 during photosynthesis is used in order to study the response of the photosynthetic process to changes in the external temperature. The model allows modeling steady, oscillatory and damped transitions between states, in relation the flows of matter and the substrate concentrations, but in order to study the effect of temperature, we added the energy balance equation to the model and we took the entire photosynthetic process to the scale of a reactor chloroplast. Variation in external temperature is carried out in different ways and. in order to analyze the photosynthetic model’s response to thermal changes; we choose the variation in the generation of entropy as the second law criteria. Results show that entropy generated during the heating process is specific to the way it’s carried out and that the system reacts more efficiently in response to a Fourier heating.
