- The Endoplasmic reticulum is a functional structure within a cell (organelle).
- It is basically a membrane enclosing a lumen (empty space) and is divided into rough endoplasmic reticululum (RER) and smooth endoplasmic reticulume (SER).
- The ER is highly convoluted which allows a large contact surface for ribosomes to attach (or reactions to occur) as well as an organized peptide storage area.
- The RER does many more things as it contains ribosomes, which are the protein-producing factories of a cell.
- The RER is therefore involved in the production storage and packaging of proteins produced in the cell and are sent to the Golgi Apparatus.
- The SER produces liposoluble molecules such as lipids, steroids and phospholipids – phospholipids are the main constituent of the cell membrane.
- Rosacea could be induced by stress on the ER (to read more, click HERE)
