So, that process happens fast but you also need this neurotransmitter release and activation to happen fast so that you can have rapid activity.

所以 电传递过程很快,但你仍需要神经递质的,快速释放和快速激活,以便使你快速活跃起来

This process, which is shown schematically here, as a vesicle fusing with the cell membrane and then dropping its neurotransmitter only happens when an action potential reaches the end of the axon.

这一过程 扼要地展示在这里,小泡同细胞膜融合,释放其神经递质,这只发生在动作电位抵达轴突末梢时

It gets produced in response to a signal so there's a binding of a ligand to a receptor, the enzyme that does this conversion is activated and more cycle AMP is released.

这类分子的产生是对信号做出的一种反应,当配体和受体结合时,催化这种转化过程的酶被激活,更多的cAMP释放出来
