If vesicles store both GABA and GHB, it is reasonable to conclude that some GABA neurotransmitters are catabolized, receptors for both GABA and GHB are found in the synaptic cleft, and the neuron releases both GABA and GHB. However, it is not reasonable to conclude that GHB does not play a role in neurotransmission for this neuron, as the presence of GHB in the vesicles suggests that it is involved in some way. Therefore, the correct answer is C.

If Vesicles Store Both GABA and GHB Molecules,then It Is
