The acclaimed explanation for mitochondrial oxidative phosphorylation (mOxPhos, or cellular respiration) is a deterministic proton-centric scheme involving four components: Rotary adenosine triphosphate (ATP)-synthesis, Chemiosmosis principle, Proton pumps, and Electron transport chain (abbreviated as RCPE hypothesis). Within this write-up, the RCPE scheme is critically analyzed with respect to mitochondrial architecture, proteins' distribution, structure-function correlations and their interactive dynamics, overall reaction chemistry, kinetics, thermodynamics, evolutionary logic, and so on. It is found that the RCPE proposal fails to explain key physiological aspects of mOxPhos in several specific issues and also in holistic perspectives. Therefore, it is imperative to look for new explanations for mOxPhos.
关于线粒体氧化磷酸化(mOxPhos,即细胞呼吸),广受赞誉的解释是一种以质子为中心的确定性机制,涉及四个组成部分:旋转式三磷酸腺苷(ATP)合成、化学渗透原理、质子泵和电子传递链(简称为RCPE假说)。在本文中,针对线粒体结构、蛋白质分布、结构 - 功能相关性及其相互作用动力学、整体反应化学、动力学、热力学、进化逻辑等方面,对RCPE机制进行了批判性分析。结果发现,RCPE假说在几个具体问题以及整体层面上都无法解释mOxPhos的关键生理方面。因此,必须寻找关于mOxPhos的新解释。
