Study Notes
Function
- Produces cellular products such as hormones and lipids, essential for forming cellular membranes.
Cell Types
- Found in eukaryotic cells, specifically in both plant and animal cells.
Location
- Located adjacent to the rough endoplasmic reticulum, close to the nucleus and Golgi apparatus.
Appearance
- Appears as a ribosome-free network, functioning like a factory for lipid synthesis.
Differences from Rough ER
- Lacks ribosomes, contrasting with rough ER, which is involved in protein assembly.
Discovery
- Discovered by Keith R. Porter, Albert Claude, Brody Meskers, and Ernest F. Fullam in 1945.
Other Functions
- In addition to lipid production, plays a role in glucose synthesis and material transport within the cell.
Metabolism
- Metabolizes natural toxins and ingested substances to detoxify the cell.
Enzymatic Reactions
- Enzymes in the smooth ER catalyze the synthesis of cholesterol, phospholipids, and steroid hormones.
Structure
- Comprises a system of membranes called cisternae, characterized by the absence of ribosomes on its surface.
