Which of the following best describes the function of synaptic vesicles?
A) The vesicle type (rather than neurotransmitter itself) determines the type and function of the neuron.
B) Vesicles spill their contents into the synaptic cleft to convert an electrical signal into a chemical signal.
C) Vesicles are intracellular sacs that bind neurotransmitters on the exterior of the vesicular membranes.
D) When an action potential is triggered, vesicles bind to the postsynaptic membrane and allow neurotransmitters to travel into the postsynaptic neuron.
