Often that signal gets amplified so it can be used, same thing happens inside cells and there's some output that's generated.
通常这些信号要放大后才会产生作用,诱发细胞内发生一些变化,并产生某种输出信号
That's what's illustrated here with the end result being that there's some change in the life of the cell.
这里显示的是,在信号放大传递后,细胞内发生的变化
The second particle was deflected almost not at all. But what he could tell from the fact that there was a second particle at all, and the fact that it was in this direction, is that in addition to his negative particle, he also, of course, had a positive particle that was within this stream of rays that were coming out.
粒子的强烈信号,有着强烈的对比,第二个粒子几乎,不发生偏转,他能判断这是,第二个粒子的原因是它在这个方向,所以在出射射线中,除了有带负电的粒子外。
There's a diverse range of responses that might occur, but that response is initiated by this simple chemical process of a ligand binding to a receptor.
细胞对外界信号可能会发生不同的反应,但这些反应都源自,配体和受体结合这个简单的化学过程
Well, what happens when the signal gets to the end of the axon?
那当信号传导至轴突末端后又会发生什么
When they receive the signal they make - they change in a very specific way and the cell can recognize this change that's occurred at the cell surface.
当它们接收到信号之后,就会发生十分特殊的变化,细胞能够识别自身表面发生的这种变化
