Umnica [9.8K]

Rough endoplasmic reticulum, Golgi apparatus, cell membrane are structures that a protein that is destined to leave the cell would interact with on its journey from synthesis to exile from the cell of his birth.

The ribosomes, which are the molecules in charge of producing proteins, are what give the rough endoplasmic reticulum its name. A specific RNA fragment may instruct a ribosome to move to the rough endoplasmic reticulum and embed itself if it comes across there. The protein produced from this region will wind up inside the rough endoplasmic reticulum, where it will fold and be marked for transport to the Golgi apparatus through the process of glycosylation, which involves the addition of a tag molecule (often a carbohydrate).

Near the nucleus, the rough endoplasmic reticulum, which is continuous with the nuclear membrane, resembles a network of canals. Rough endoplasmic reticulum-produced proteins are either meant to form a membrane or to be released from the cell membrane. It would be much more difficult to discern between proteins that should exit the cell and proteins that should remain if there were no rough endoplasmic reticulum. As a result, the rough endoplasmic reticulum promotes cell specialization and increases organism complexity.
