Question

Quizplus · Accepted Answer

Synaptic vesicles are docked to the plasma membrane of the axon terminal by a protein complex called SNARE (Soluble NSF Attachment Protein Receptor). Synaptotagmins are calcium-binding proteins that play a role in neurotransmitter release, but they are not directly involved in docking the vesicles. Boutons are small swellings on the axon terminal where synapses occur, but they are not involved in docking vesicles. Connexons are protein channels that allow for communication between cells, but they are not involved in synaptic vesicle docking.
