Abstract:
The model of potential dependent proton transfer trough the cell membrane of Chara alga developed in [1] is considered. In the last version of the model we considered two variables: proton concentration near the surface cell and transmembrane potential. In present version we introduce the new variable — proton concentration in cytoplasm. Oscillative and chaotic dynamic of transmembrane potential was obtained in calculations. The physiological role of these patterns is discussed.
Keywords:
