A model and computation for oscillatory phenomena observed in some biological processes that utilize ion gradients across a membrane is presented. The model contains two main features: (i) active H+ transport pathways in the membrane and (ii) key enzymes having a pH-dependent activity profile and either translocating H+ from outside or producing H+ as a product. With this model a very long period of oscillations, as observed in mitochondrial and circadian rhythms, could be quantitatively demonstrated.
本文提出了一个模型及计算方法,用于描述在一些利用跨膜离子梯度的生物过程中观察到的振荡现象。该模型包含两个主要特征:(i)膜中的主动H⁺转运途径;(ii)具有pH依赖性活性曲线且能将H⁺从外部转运或产生H⁺作为产物的关键酶。利用这个模型,可以定量地证明线粒体和昼夜节律中观察到的非常长周期的振荡。
