Question

5. Differentiste between rough and smooth
endoplasmic reticulum? How is endoplasmic
reticulum important for membrane
biogenesis?​

Answer 1

Answer:

RER has particles of ribosome on the surface, therefore are rough in texture.

Explanation:

Endoplasmic reticulum synthesizes lipids (smooth endoplasmic reticulum) and proteins (rough endoplasmic reticulum) which are responsible for formation of membrane. Thus, they help in membrane biogenesis.

hope u got it...

thank me...

Answer 2

The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface
