Secondary Messenger Model. Second messenger systems are a means of transmitting signals from receptors on the cell surface to target molecules. The greatest benefit of second messengers is speed and amplification.

But in addition to their job as relay molecules second messengers serve to greatly amplify the strength of the signal.
Binding of a ligand to a single receptor at the cell surface may end up causing massive changes in the biochemical activities within the cell. Secondary messengers are a component of signal transduction cascades. Formation of camp and cgmp is catalyzed by the enzymes adenylyl cyclase and guanylyl cyclase respectively. Second messenger systems are a means of transmitting signals from receptors on the cell surface to target molecules.
