That just allows information to move more quickly from one end of the cell to the other.
鞘磷脂使信息更快地,从细胞一端传递到另一端
-
Then that information - that integrated information is passed onto another cell through the axon.
然后信息 - 整合好的信息,通过轴突传递给下一个细胞
-
It indicates how information flows in cells and indicates a lot about the work that a cell does in maintaining and recreating itself, and maintaining its environment.
这个图展示了信息如何在细胞内传递,以及细胞,在维持 复制自身,和维持其周围环境所需起的作用
-
It doesn't work that way for a variety of reasons, but the main reason is that you want some decisions to be made at each space between two cells.
这出于很多原因,但主要的原因是,在每个细胞间隙,都需要决定信息是否继续传递
-
If you hear about signal transduction in biology, people that study signal transduction are studying just these things we talked about, how biochemical messages get transferred into cells and through cells.
如果你在生物学领域听到信号转导这个词,那么研究信号转导的人就是,在研究我刚才讲过的那些东西,生化信息如何传入细胞并传递至细胞各处
-
The way that they communicate with each other is by physically touching each other, and the way that they connect across distances is by having these process that extend from one place to another.
它们通过物理接触,来交换信息,神经之所以能跨距离传递信息,就是靠细胞间互相延伸的突起
-
Well, the mechanism that the cell uses to transmit information along itself, along this process which goes from my brain to my fingers, for example, is through an electrical signal called an action potential.
神经细胞沿突起,将信息从我的大脑传递到,手指的机制是,举例来说,是通过一种称为动作电位的电信号的作用
-
We're going to talk in some detail, not a very high level of detail, but in some detail about how this communication takes place between cells and how the information is passed down one of these cells today.
我们还要讨论些细节问题,但不是太深,今天只讲细胞间通讯的发生原理,和信息怎样从一个细胞传递到另一个细胞
-
Because these molecules can span across the membrane from outside to inside, they're in just the right position to take messages that they receive from outside the cell and transmit them through the membrane into the cells internal apparatus, and that's what they do.
因为这些分子能穿过细胞膜,连通细胞内外,它们所在的位置非常适于接受信息,它们能将外界获得的信息,通过细胞膜传递给细胞器,这正是它们的功能
