Fusion of Small Synaptic Vesicles with the Pre-Synaptic Membrane Requires

Question

Fusion of small synaptic vesicles with the pre-synaptic membrane requires A) tubulin B) kinesin C) clathrin D) dynamin E) Ca²⁺

Accepted Answer

The correct answer involves a typographical error meant to represent "Calcium ions" or "Ca2+." The fusion of synaptic vesicles with the presynaptic membrane is triggered by an influx of calcium ions into the nerve terminal upon depolarization. This process is essential for the release of neurotransmitters into the synaptic cleft.
