Question

Answer 1

Synaptic vesicle docking and fusion at the axon terminal membrane involve SNARE proteins. V-SNARE and T-SNARE proteins facilitate this process, leading to neurotransmitter release into the synaptic cleft and subsequent signal transmission.

Step-by-step explanation:

The docking of synaptic vesicles at the axon terminal membrane and their fusion with the membrane requires the interaction of multiple proteins, specifically SNARE proteins. V-SNARE proteins on the vesicles bind to complementary T-SNARE proteins on the presynaptic membrane to facilitate the fusion of vesicles. Once fused, the vesicles release neurotransmitters into the synaptic cleft, an extracellular space between presynaptic and postsynaptic membranes. The neurotransmitter molecules then diffuse across the synaptic cleft and bind to receptor proteins on the postsynaptic membrane, completing the transmission of the neural signal.
