Overview
The endoplasmic reticulum (ER) is a vital organelle in eukaryotic cells, consisting of a network of membranes that facilitate the synthesis and transport of proteins and lipids. The rough ER, characterized by ribosomes on its surface, is primarily involved in protein synthesis, while the smooth ER p...
Key Terms
Example: The endoplasmic reticulum is found in all eukaryotic cells.
Example: The rough ER is responsible for producing proteins for export.
Example: The smooth ER helps in synthesizing hormones.
Example: Ribosomes can be found on the rough ER.
Example: Smooth ER plays a key role in lipid metabolism.
Example: Chaperone proteins assist in protein folding in the ER.
