跨膜运输过程在任何生物系统中起着核心作用。它们对于体内平衡、细胞营养和信号传导是必不可少的。跨膜通量受基本热力学规则支配，并受电势和浓度梯度的影响。跨膜转运过程已经在单膜上进行了大量研究。然而，一些重要的细胞或亚细胞结构由两个紧密间隔的膜组成，形成膜夹层。这样的双膜结构导致了在分离膜中不存在的用于运输过程的显著性质。在膜夹层性质的核心，小的膜间体积负责在两个独立膜处的运输系统之间的有效耦合。在这里，我们提出的物理化学原理的运输耦合在两个相邻的膜，并说明这一概念与三个例子。在补充材料中，我们提供了动画PowerPoint演示文稿，将这些关系可视化。它们可以用于教学目的，塔尔卡大学已经成功地完成了这一工作。
Transport processes across membranes play central roles in any biological system. They are essential for homeostasis, cell nutrition, and signaling. Fluxes across membranes are governed by fundamental thermodynamic rules and are influenced by electrical potentials and concentration gradients. Transmembrane transport processes have been largely studied on single membranes. However, several important cellular or subcellular structures consist of two closely spaced membranes that form a membrane sandwich. Such a dual membrane structure results in remarkable properties for the transport processes that are not present in isolated membranes. At the core of membrane sandwich properties, a small intermembrane volume is responsible for efficient coupling between the transport systems at the two otherwise independent membranes. Here, we present the physicochemical principles of transport coupling at two adjacent membranes and illustrate this concept with three examples. In the supplementary material, we provide animated PowerPoint presentations that visualize the relationships. They could be used for teaching purposes, as has already been completed successfully at the University of Talca.
