Question

difference between SER and RER​

Answer 1

Smooth ER

The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most eukaryotic cells. ... Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell

Rough ER

The rough endoplasmic reticulum (rough ER) is a part of the endomembrane system of the cell and a subset of the endoplasmic reticulum (ER). ... The rough ER is characterized by the presence of membrane-bound ribosomes that give it a distinctive appearance under the microscope.

Answer 2

HLO MATE HERE U GO.

❤. Smooth endoplasmic reticulum ❤

• The endoplasmicreticulum which does not contains ribosomes on their surface is called SER.
• SER is the site for synthesis of lipids and lipids like steroidal hormones in animal cells.

❤. Rough endoplasmic reticulum ❤

• The ER bearing ribosomes on their surface is called RER.
• RER observed in cells actively involves in protein synthesis and secretion.
