摘要

在最近发表的一篇文章中,Hernansanz-Agusti̒n 等人提出,线粒体内膜上的钠梯度是由与复合体 I 不可分割的 Na+/H+ 活性产生的,可以占线粒体膜电位的一半。这与传统的电生理学和化学渗透理解相冲突。

Does a transmembrane sodium gradient control membrane potential in mammalian mitochondria?
In a recent publication, Hernansanz-Agusti̒n et al. propose that a sodium gradient across the inner mitochondrial membrane, generated by a Na+/H+ activity integral to Complex I can account for half of the mitochondrial membrane potential. This conflicts with conventional electrophysiological and chemiosmotic understanding.
