What is smooth Endoplasmic reticulum?

2 Answers

The endoplasmic reticulum without ribososmes.


  1. The endoplasmic reticulums are two types, the rough endoplasmic reticulum and smooth endoplasmic reticulum.
  2. The endoplasmic reticulum without ribososmes is known as smooth endoplasmic reticulum or simply SER, while rough endoplasmic reticulum or simply RER contains ribosomes. The endoplasmic forms cytoskeleton.
  3. The smooth endoplasmic reticulum is associated with fat and steroid metabolism.
  4. The RER is the site of protein synthesis. Thank you

The smooth endoplasmic reticulum lacks ribosomes and functions in lipid metabolism, production of steroid hormones and detoxification.


The Endoplasmic reticulum is a type of organelle in eukaryotic cells that forms an interconnected network of flattened , membrane enclosed sacs or tube like structures known as cisternea.

The network of smooth Endoplasmic reticulum allows for an increased surface area, to be devoted to the action or storage of key enzymes and the products of these enzymes.

It also carries out the metabolism of carbohydrates , detoxification of natural metabolism products and of alcohol and drugs, attachment of receptors on cell membrane proteins.
