Endoplasmic reticulum (ER) is a network of membrane-bound organelles found in the cytoplasm of eukaryotic cells. It plays a crucial role in the synthesis, folding, and modification of proteins, as well as the synthesis and transport of lipids. The ER is divided into two main regions: the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER).
The RER is characterized by the presence of ribosomes attached to its surface, which are responsible for
The ER is also involved in the synthesis of certain molecules, such as steroids and phospholipids, which
In summary, the endoplasmic reticulum is a vital organelle in eukaryotic cells, responsible for protein synthesis,
