The endoplasmic reticulum (ER) is the membrane-bound organelle responsible for the synthesis of proteins and lipids. It exists in two forms:
1. **Rough Endoplasmic Reticulum (RER)**: Studded with ribosomes on its cytoplasmic surface, the RER is primarily involved in the synthesis and initial folding of proteins that are either secreted from the cell, incorporated into the cell's plasma membrane, or sent to an organelle.
2. **Smooth Endoplasmic Reticulum (SER)**: Lacking ribosomes, the SER is involved in the synthesis of lipids, metabolism of carbohydrates, detoxification of drugs and poisons, and storage of calcium ions.
Both types of ER play crucial roles in cellular function and the overall synthesis of biomolecules.
