Explanation:
1. Signal transduction also called as cell signaling, it is the transmission of molecular signals from outside side of the to its interior side.
2. Signals received by cells specifically and must be transmitted effectively into the cell and, function correctly.
3. The signal is first attach to the cell-surface receptors in a specific manner. And then with the help of various proteins, they reach to their final target and show their effect.
4. Most of the signal transduction pathways contain multiple steps, the reason is that multiple steps provide for greater possible amplification
of a signal.
