The Smooth Endoplasmic Reticulum

• Found in the cytoplasm of most eukaryotic cells, unattached to nucleus
• The size is variable depending on the cell and it’s function
• Its function is the synthesis and transport of some lipids and steroids and the storage and release of calcium in skeletal muscle cells.
• Contain enzymes that play a large role in the detoxifying (making harmless) of poisonous organic molecules. (ie drugs)
• The structure of the SER increases the surface area for reactions, synthesis and storage. It is believed that in 1ml of liver tissue there is around 11m² of SER.
