Normal Dopamine molecule binds to a Dopamine receptor (in pink).  After the Dopamine binds, it comes off the receptor and is removed from the synaptic cleft by uptake pumps (also proteins) that reside on the terminal (arrows show the direction of movement).  This process is important because it ensures that not too much Dopamine remains in the synaptic cleft at any one time.  There are neighboring neurons that release another compound called a neuromodulator.  Neuromodulators help to enhance or inhibit neurotransmission that is controlled by neurotransmitters such as Dopamine.   In this case, the neuromodulator is an "endorphin" (in red).  Endorphins bind to opiate receptors (in yellow) which can reside on the post-synaptic cell (shown here) or, in some cases, on...
