Question

where do the lipids and proteins proteins constituting the cell membrane get synthesised​

Answer 1

$\huge\mathfrak{Answer:-}$

SER (Smooth endoplasmic reticulum) helps in the synthesised of lipids and RER are the site for protein synthesised as they contain ribosomes on their surface.

Answer 2

Hey Mate !!!!

Lipids present in the cell membrane are synthesized in the smooth endoplasmic reticulum which does not contain the ribosomes.

However, the proteins are produced in the rough endoplasmic reticulum, which is called so because it has the ribosomes attached to the endoplasmic reticulum. Ribosomes help in protein synthesis.
