Principles of regulation on different levels of photosynthetic apparatus are discussed. Mathematical models of isolated photosynthetic reaction centers and general system of energy transduction in chloroplast are developed. A general approach to model these complex metabolic systems is suggested. Regulatory mechanisms in plant cell are correlated with the different patterns of fluorescence induction curve at different internal physiological states of the cells and external (environmental) conditions. Light regulation inside photosynthetic reaction centers, diffusion processes in thylakoid membrane, generation of transmembrane electrochemical potential, coupling with processes of CO(2) fixation in Calvin Cycle are considered as stages of control of energy transformation in chloroplasts in their connection with kinetic patterns of fluorescence induction curves and other spectrophotometric data.
讨论了光合装置不同层次的调控原理。建立了分离的光合反应中心的数学模型以及叶绿体能量转导的一般系统。提出了一种对这些复杂代谢系统进行建模的通用方法。植物细胞中的调控机制与细胞在不同内部生理状态和外部(环境)条件下荧光诱导曲线的不同模式相关。光合反应中心内部的光调控、类囊体膜中的扩散过程、跨膜电化学势的产生、与卡尔文循环中CO₂固定过程的耦合,被视为叶绿体能量转化控制的阶段,它们与荧光诱导曲线的动力学模式及其他分光光度数据相关。
