从生物物理学的观点来看 ,离子通道应具有三个最重要性质 :通透性、选择性及门控机制。离子通道是以该通道允许通透的主要离子命名的 ,门控机制则调节着该离子的流动过程。细胞膜离子通道根据其门控机制可以分为三类 :电压门控性通道、配体门控性通道以及机械敏感性通道。另外 From the biophysical point of view, ion channels should have the three most important properties: permeability, selectivity and gating mechanisms. The ion channel is named after the main ion that this channel allows to permeate, and the gating mechanism regulates the flow of this ion. Membrane ion channels can be divided into three categories according to their gating mechanisms: voltage-gated channels, ligand-gated channels, and mechanosensitive channels. In addition
