What type of membrane transport is used in the following scenario?
a) neurons will release signaling molecules called neurotransmitters in order to communicate with other neurons or with organs.
b) in the axon terminal of many neurons are storage vesicles of these neurotransmitters called synaptic vesicles.
c) when an electrical signal known as an action potential is propagated to the axon terminal, the synaptic vesicles fuse with the neuronal membrane and the neurotransmitter is released.
