A photosynthetic process modelled by a metabolic P system

Photosynthesis is the process used by plants, algae and some bacteria to obtain biochemical energy from sunlight. It is the most important process allowing life on earth. In this work, by applying the Log Gain theory of Metabolic P Systems, we define a mathematical model of an important photosynthetic phenomenon, called Non Photochemical Quenching (shortly NPQ), that determines the plant accommodation to the environmental light. Starting from experimental data of this phenomenon, we are able to deduce a Metabolic P system which provides, in a specific simplified case, the regulation mechanism underling the NPQ process. The dynamics of our model, generated by suitable computational tools, reproduce, with a very good approximation, the observed behaviour of the natural system.
