Insulin, the ligand binds to its receptor, creates a change through a kinase activity that's exposed, which leads to other biochemical changes, which leads to a change in cell behavior - in this case the cell behavior is that more glucose transporters are brought to the membrane and more glucose can enter the cell.

胰岛素,一种能够与受体结合的配体,通过其暴露出的激酶活性引起的变化,导致了其它后续生化变化的发生,进而使细胞行为发生改变,这个例子中的细胞行为就是,更多的糖载体被带到细胞膜表面,这样更多的糖分子进入到细胞内部
