Modelling Giant Lipid Vesicles Designed for Light Energy Transduction

In this paper a deterministic kinetic model describing giant lipid vesicles designed for the transduction of light into chemical energy will be presented and discussed. Although the model is based on a simplified mechanism, kinetic constants taken from experimental measurements have been used. The obtained results have shown that giant vesicles encapsulating the Reaction Center in the lipid membrane can exhibit, in suitable experimental conditions, a sensible increase of the internal pH in half an hour under a constant light irradiation.
