question 21

Multiple Choice

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.
