Signal Transduction - The process of converting signals from one form to another. In cells: 
Extracellular signaling molecule --> receptor --> intracellular signaling molecules --> effector proteins 
Extracellular Signaling Molecules - this type of signaling molecule comes from outside of the cell, 
and can come in many different forms 
Receptor - this is a generic term for what binds a ligand 
Intracellular signaling molecule - as a result of a receptor being bound, this is released in...
