Overview
The Rough Endoplasmic Reticulum (RER) is a vital organelle in eukaryotic cells, primarily responsible for the synthesis and processing of proteins. Its rough appearance is due to the ribosomes attached to its surface, which play a crucial role in translating messenger RNA into polypeptides. Once syn...
Key Terms
Example: The endoplasmic reticulum is divided into rough and smooth types.
Example: Ribosomes can be found free in the cytoplasm or attached to the RER.
Example: Proper protein folding is essential for the protein's function.
Example: Glycosylation is a common post-translational modification.
Example: Proteins from the RER are sent to the Golgi apparatus for further processing.
Example: Ribosomes float freely in the cytoplasm or are attached to the RER.
