Draw a typical axodendritic synapse, including a specific neurotransmitter of your choice, its associated postsynaptic receptors (indicating whether they are ionotropic or metabotropic), and any associated reuptake transporters or degradation enzymes. Please include a description of what specific steps would occur as an action potential reaches the axonal terminal.
