Advances in systems biology and whole-cell modelling demand increasingly comprehensive mathematical models of cellular biochemistry. Such models require the development of simplified representations of specific processes which capture essential biophysical features but without unnecessarily complexity. Recently there has been renewed interest in thermodynamically-based modelling of cellular processes. Here we present an approach to developing of simplified yet thermodynamically consistent (hence physically plausible) models which can readily be incorporated into large scale biochemical descriptions but which do not require full mechanistic detail of the underlying processes. We illustrate the approach through development of a simplified, physically plausible model of the mitochondrial electron transport chain and show that the simplified model behaves like the full system.
系统生物学和全细胞建模的进展需要越来越全面的细胞生物化学数学模型。此类模型需要开发特定过程的简化表示，以捕捉基本的生物物理特征，但又不过度复杂。最近，人们对基于热力学的细胞过程建模重新产生了兴趣。在此，我们提出一种方法来开发简化但热力学一致（因此在物理上合理）的模型，这些模型可以很容易地纳入大规模生化描述中，但不需要底层过程的完整机制细节。我们通过开发线粒体电子传递链的简化、物理上合理的模型来说明该方法，并表明简化模型的行为与完整系统相似。
