蛋白激酶与蛋白磷酸酶在细胞信号传递中起着重要作用。
Protein kinases and phosphatases play a central role in cellular signaling.
They often involve the generation of what are called 'second messenger' molecules which carry the signal further into the cell.
过程中通常会生成一种叫做,第二信使的分子,将信号更深入地传递至细胞内部
This is a signal - this passing of phosphorous - is a signal that's used very frequently in intracellular communication.
这是一种信号,一种通过磷酸来传递的信号,这种信号在细胞内通讯时经常被用到
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
