While characterizing the activities of several neurons, you find a neuron with the following properties:

(1) When stimulated, the neuron fails to release neurotransmitters into the synaptic cleft.
(2) Microinjection of calcium ions calcium ions has no effect on the neuron. (In other neurons such microinjection stimulates the t-SNARE and v-SNARE complex interaction that promotes neurotransmitter secretion.)
The abnormality in this neuron is most likely associated with the function of
A) the vesicle membranes.
B) acetylcholinesterase.
C) synaptotagmin.
D) GABA receptors.
E) gap junctions.
