离子通道存在开放与关闭两种状态,由控制闸门决定,闸门的变化使通道开放或关闭的过程称为门控。一般情况时,离子通道处于关闭状态,只在一定的条件下开放。由关闭转为开放的过程称为激活,由开放转为关闭的过程称为失活。 There are two kinds of ion channel open and closed state, the decision by the control gate, gate changes make the channel open or closed process is called gating. Under normal circumstances, the ion channel is off, only open under certain conditions. From closed to open process called activation, from open to closed process called deactivation.
