电压门控通道:应用类似的技术,在80年代还陆续克隆出几种重要离子(如Na+、K+和Ca2+等离子)的电压门控通道,它们具有同化学门控能道类似的分子结构,但控制这类通道开放与否的因素,是这些通道所在膜两侧的跨膜电位的改变;也就是说,在这种通道的分子结构中,存在一些对跨膜电位的改变敏感的基团或亚单位,由后者诱发整个通道分子功能状态的改变。
电压门控通道(voltage-gated channel ) : 电压控制通道则是在外界电压到达一定程 度时,通道蛋白去极化而被打开。

That change happens because something gets triggered in the membrane, and what gets triggered is a voltage gated sodium channel, which is shown here.
变化的原因是膜上某些东西被触发了,被触发的是钠离子电压门控通道,展示在这儿了
Now, remember we talked about these last time, voltage-gated channels are channels that would allow the passage of sodium, in this case, but they can exist in two states, a closed state and an open state.
还记得我们上节课讨论过的吧,电压门控通道是,一种可以容许钠离子通过的通道,在这一例子中 电压门控通道有两种状态,关闭状态和开放状态
