Which step is NOT involved in neurotransmitter release at a synapse?
1 . creation of a fusion pore
2. hemifusion induced by zipping and lateral tension on the bilayers
3 . v-SNARE binding to t-SNARE
4 . pore widening and release of neurotransmitter
5. flippase-mediated movement of phosphatidylserine from the inner to the outer
(plz explain)

All membrane translocations occurring in eukaryotic cells involve the formation of fusion pores. Through fusion pores, cells fuse lipid bilayers and target proteins from one cellular compartment to the next in membrane trafficking. In addition, fusion pores represent a key target for intracellular messenger regulation.
