Фундаментальный учебник по биофизике. В первом томе даны теоретические основы современной биофизики Часть 1 "Биофизика сложных систем" посвящена проблемам математического моделирования биологических процессов и термодинамическим аспектам биологических систем вблизи равновесия (линейная термодинамика) и вдали от равновесия (нелинейная термодинамика). В части "Молекулярная биофизика" описаны физические особенности, динамические и электронные свойства структурной единицы живого - макромолекулы, а также физико-химические механизмы трансформации энергии в биоструктурах.
Based on up-to-date physicochemical data, a complete kinetic model of the catalytic cycle of photosystem II (PS II) for higher green plants was constructed. In compliance with the time hierarchy of photosynthetic stages, the model was reduced in order to describe only processes occurring on the millisecond time scale. In terms of the model, chlorophyll fluorescence induction curves at different values of model parameters were calculated. The fluorescence intensity was determined from an equation for calculating the concentrations of PS II fluorescence states and their dependence on the components of the electrochemical potential across the tylacoid membrane. The proposed model, which considers only processes occurring within PS II, cannot describe some features of the ascending branch of the chlorophyll fluorescence induction curve. It was found that the steady-state level of the fluorescence intensity may nonmonotonically depend on the transmembrane electric potential.
