What exactly is the role of the cell membrane in the production of proteins?

Question

This is all I have on the production of proteins. How does the cell membrane contribute to this production?

The cell membrane is made of a lipid bilayer with embedded proteins (Comment: In the paragraph below, where should I put this?)

Ribosomes inside a cell make proteins on the surface of the rough endoplasmic reticulum (ER) - an extensive system of internal membranes that move proteins and other substances through the cell. Each protein made by the ribosomes attached on the rough ER then enters the smooth ER and are packed into vesicles. These vesicles carry the proteins from the rough ER to the Golgi apparatus for modifying and packaging (into new vesicles). Many of these vesicles move to the cell membrane and release their proteins outside the cell.

Answer 1

You should indicate that the membrane of the vesicle fuses with the cell membrane and the proteins are released via exocytosis.
