The two steps are as follows:<br /> <br /> # A signaling molecule (outside the cell) activates a [[cell surface receptor]] located on the [[cell membrane]] (and hence capable of interacting with the molecule).<br /> # A messenger molecule transmits the signal from the cell membrane in&#039;&#039;to&#039;&#039; the cell and elicit a physiological response within the cell.<br /> <br /> The pathways by which this happens are termed &#039;&#039;&#039;signal transduction pathways&#039;&#039;&#039;.</div>
