When an action potential reaches the axon terminal, what is the proper order of events in which exocytosis of the neurotransmitter takes place? A. Ligand-gated Na+ channels open and Na+ rushes into the axon terminal; Na+ binds with synaptotagmin and together they activate the SNARE/vesicle complex, which docks and allows the neurotransmitter-filled vesicle to be exocytosed. B. Voltage-gated Na+ channels open and Na+ rushes into the axon terminal; Na+ binds with synaptotagmin and together they activate the SNARE/vesicle complex, which...
