True about synaptic vesicle is 
Select and explain. 
A. Small Clear vesicle contain ACh & GABA, B. Small vesicle contain neuropeptides, C. Large vesicle contain dense core with glutamate, D. Small clear vesicle contain neuropeptides
A: Small Clear vesicle contain ACh & GABA
Answer: A: Small Clear vesicle contain ACh & GABA 
Explanation: (A) Small Clear vesicle contain Ach & GABA # Inside the presynaptic terminal are many mitochondria, as well as many membrane-enclosed vesicles, which contain neurotransmitters. There are three kinds of synaptic vesicles: Clear synaptic vesicles that contain acetylcholine, glycine, GABA, or glutamate; small vesicles with a dense core that contain catecholamines; and large vesicles with a dense core that contain neuropeptides.
