Detailed explanation-1: -The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Detailed explanation-2: -ROUGH ENDOPLASMIC RETICULUM These are called membrane bound ribosomes and are firmly attached to the outer cytosolic side of the ER About 13 million ribosomes are present on the RER in the average liver cell. Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus.
Detailed explanation-3: -Final Answer: Ribosomes are attached to the endoplasmic reticulum through a glycoprotein known as Ribophorin I and II.
Detailed explanation-4: -[6] Ribosomes, along with their subunits, are a characteristic of the RER and can help identify it. However, these proteins are also found free-floating throughout the cytoplasm and other parts of the cell.
Detailed explanation-5: -The rough ER, which is covered by ribosomes on its outer surface, functions in protein processing. The smooth ER is not associated with ribosomes and is involved in lipid, rather than protein, metabolism.
