Nonlinear dynamic of the transmembrane potential and pH along the cell membrane of Chara alga

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.
