Answer

3 stages of cell signaling: Reception: Target cell is contacted by the signal as it reaches receptors on either the cell surface or interior. Transduction: Binding of signal triggers the receptor protein of the target cell and thus kick-starts the process of transduction. Response: Transduced signal triggers a cellular response that can range from secreting an enzyme to activating specific genes.
