A mathematical model of potencial-dependent proton transfer across the membrane of Chara corallina cells is considered. To construct the model, partial differential equations describing the system dynamics in time and in space were used. The variables of the model are the proton concentration and membrane potential. The model describes the experimentally observed inhomogeneous distribution of transmembrane potential and pH along the membrane and oscillations of the potential and pH in time. A mechanism of the distribution of pH and membrane potential along the Chara corallina cell is suggested.
本文考虑了莱茵衣藻细胞跨膜质子转移的电位依赖数学模型。为构建该模型,使用了描述系统时空动态的偏微分方程。模型变量为质子浓度和膜电位。该模型描述了实验观察到的跨膜电位和pH沿膜的不均匀分布以及电位和pH随时间的振荡。本文提出了莱茵衣藻细胞pH和膜电位沿细胞分布的机制。
