细胞代谢数学模型中奇异吸引子混沌的结构

The structure of a chaos of strange attractors within a mathematical model of the metabolism of a cell

V. I. Grytsay, I. V. Musatenko

摘要:

这项工作继续研究早期构建的数学模型的代谢过程中运行的细胞。我们将考虑在营养和呼吸链中酶-底物相互作用水平上产生的自振荡,这导致细胞中整体代谢过程的自催化中的自组织。自动振荡在自动催化下在细胞的总代谢过程中组织自己。本文分析了动力学膜电位在高耗散情况下的相位参数特性。研究了系统所有可能的振荡模式以及规则吸引子和奇异吸引子的形成和破坏情况。计算了“有序-混沌”、“混沌-有序”、“混沌-混沌”和“有序-有序”跃迁的分岔。的总谱的李雅普诺夫指数和发散的所有类型的吸引子的一部分的相位参数特性的考虑。对于不同类型的奇异吸引子,计算了它们的李雅普诺夫维数、KS熵和“可预报性视界”。得出了关于奇异吸引子混沌结构及其对细胞代谢过程稳定性影响的一些结论。

英文摘要:

This work continues the study of the earlier constructed mathematical model of the metabolic process running in a cell. We will consider auto-oscillations arising on the level of enzyme-substrate interactions in the nutrient and respiratory chains, which leads to the self-organization in autocatalysis of the integral metabolic process in cells. The auto-oscillations organize themselves in the total metabolic process of cells at autocatalysis. The behavior of the phase-parametric characteristic under the high dissipation of a kinetic membrane potentialis analyzed. All possible oscillatory modes of the system and the scenario of formation and destruction of regular and strange attractors are studied. The bifurcations of the transitions "order-chaos", "chaos-order", "chaos-chaos" and "order-order" are calculated. The total spectra of Lyapunov indices and the divergences for all types of attractors on a part of the phase-parametric characteristic under consideration are determined. For various types of strange attractors, their Lyapunov dimensions, KS-entropies, and "predictability horizons" are calculated. Some conclusions about the structure of the chaos of strange attractors and its influence on the stability of the metabolic process in a cell are drawn.
