WebbThe two-messenger mechanism of hormone action involves “messengers” that make something happen, that is, stimulate specific reactions. Protein hor-mones usually bond to receptors of the cell mem-brane, and the hormone is called the first messenger.

WebbCell-surface receptors are membrane-anchored proteins that bind to ligands on the outside surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands.
