Which is the correct sequence of modification and transport of secretory vesicles?

Options

  1. ARER Cell membrane Secretory vesicles Golgi body
  2. BRER Secretory vesicles Cell membrane
  3. CRER Cell membrane Secretory vesicles Golgi body
  4. DSER Golgi body Cell membrane Secretory vesicles

Correct answer

B. RER Secretory vesicles Cell membrane

Step-by-step solution

The correct sequence of modification and transport of secretory vesicles is follows RER Golgi body Secretory vesicles Cells membrane Protein destined for secretion are made on ribosomes bound to the RER. The proteins move through the endomembrane system and are dispatched from the trans face of the Golgi apparatus in transport vesicles that move through the cytoplasm and then fuse with the plasma membrane releasing the protein to the outside of the cell.
