Question

Function of secretory vesicle

Answer 1

Answer:

The secretory vesicle is a vesicle that mediates the vesicular transport of cargo - e.g. hormones or neurotransmitters - from an organelle to specific sites at the cell membrane, where it docks and fuses to release its content.

Answer 2

Answer:

1) Secretory vesicles in the regulated secretory pathway carry soluble proteins, peptides or neurotransmitters and are actively transported to selected subcellular domains for extracellular delivery in response to a specific extracellular signal.

2) In addition to transportation, secretory vesicles can store or digest certain secreted molecules.

3) Synaptic vesicles store neurotransmitters, hormones are stored in secretory vesicles for release into the bloodstream, and enzymes are also stored in secretory vesicles to be used when needed to make cell walls in certain plants, fungi, and bacteria.
