减少钠离子通道可减弱信号,从而节约能量。
By using fewer sodium channels, the signal gets dimmed and energy is conserved.
而离子通道已知能够调节神经元之间的信号。
Ion channels are known to regulate signaling between such neurons.
However, when that gate is opened, the sodium channel is now going to be incredibly selective and only let through sodium ions and no other type of ion.
但是,当闸门打开的时候,钠离子通道,将会有极高的选择性,不允许除钠离子以外的任何其它离子通过。
And all ion channels are selective for a single type of ion, and we can think about how that selectivity takes place, and that's where this idea of atomic radius is going to become very important.
所有的离子通道都是仅对某一种离子具有选择性的,而我们可以来想一想这种选择性是如何发生的,这也就是原子半径这个概念将会变得,非常重要的地方。
The ones that are most important in physiology are ones that only allow ions to go through: sodium, potassium, chloride, calcium, bicarbonate.
在生理学上这种,只能允许某种离子通过的通道十分重要,这些离子包括钠离子,钾离子,氯离子,钙离子和碳酸氢根离子
