Rough Endoplasmic Reticulum

The Rough Endoplasmic Reticulum (ER) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is composed of flattened sheets of membranes and serves several important functions in the cell. The primary role of the Rough ER is to modify and transport proteins that are synthesized in the cytoplasm. It is also involved in lipid biosynthesis and the production of certain hormones and enzymes. The Rough ER plays a key role in maintaining cellular homeostasis and is an essential part of the cell’s endomembrane system. It is also known to be involved in the development of various diseases including cancer, diabetes, and cardiovascular diseases.
