Detailed explanation-1: -Conclusion: A series of membrane-enclosed channels studded with ribosomes is called Rough endoplasmic reticulum.
Detailed explanation-2: -The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.
Detailed explanation-3: -The RER is associated with many roles in protein synthesis, which also include post-translational modifications, folding, and sorting. Membrane-bound ribosomes in the RER translate the mature mRNA transcript into amino acids that are attached to become polypeptides.
Detailed explanation-4: -The outer surface of the endoplasmic reticulum can be smooth or rough. The rough endoplasmic reticulum has many ribosomes on its outer surface and makes proteins the cell needs. The smooth endoplasmic reticulum makes other substances that the cell needs, such as lipids (fats) and carbohydrates (sugars).
Detailed explanation-5: -Key Points. If the endoplasmic reticulum (ER) has ribosomes attached to it, it is called rough ER; if it does not, then it is called smooth ER. The proteins made by the rough endoplasmic reticulum are for use outside of the cell.
