Question

what is the difference between smooth endoplasmic reticulum and rough endoplasmic reticulum​

Answer 1

$\huge{\underline{\underline{\sf{Endoplasmic \ Reticulum}}}}$

Endoplasmic Reticulum is a network of fine tubes and tubules arranged in the cytoplasm of an eukaryotic cell

★ER is situated around the nucleus of the cell

★On the basis of presence of ribosomes,it can be divided into rough endoplasmic reticulum and smooth endoplasmic reticulum

Rough Endoplasmic Reticulum

• RER is rough on its surface because of the presence of ribosomes

• It is actively involved in protein synthesis

• The proteins synthesized by the RER eventually become glycoproteins and are transported outside of the cell

• Gives rise to the SER

Smooth Endoplasmic Reticulum

• Ribosomes aren't present on the SER,thus accounting for their smooth surface

• They perform Lipogenesis,i.e.synthesis of lipids

• The lipids they produced are involved in Membrane Biogenesis and Detoxification of drugs

Answer 2

Answer:

ER is situated around the nucleus of the cell

ER is situated around the nucleus of the cellOn the basis of presence of ribosomes,it can be divided into rough endoplasmic reticulum and smooth endoplasmic reticulum.
