- The intracellular small molecules which can transmit extracellular signal is called ( ) A: first messenger B: carrier C: second messenger D: transmitter E: third messenger
- How a cell reacts to a signal depends on the set of intracellular signaling molecules each cell-surface receptor produces and how these molecules alter the activity of effector proteins, which have a direct effect on the behavior of the target cell.
- Amplification results when an enzyme associated with a signal receptor is activated and, in turn, catalyzes the activation of many molecules of a second enzyme, each of which activates many molecules of a third enzyme, and so on, in a so-called _____________________.
- 第二信使 ( second messenger )
- The second messenger that activates PDK is? ( )
