This fact sheet is for the video Understanding the Endoplasmic Reticulum: Rough vs Smooth ER and Protein Import.
The cell contains two types of endoplasmic reticulum (ER): rough and smooth. The rough ER, studded with ribosomes, is involved in protein production, while the smooth ER, which lacks ribosomes, is responsible for vesicle formation to transport proteins and lipids to the Golgi apparatus. Additionally, the ER plays a critical role in protein glycosylation and quality control, ensuring proper folding and degradation of misfolded proteins.
