Which of the following events does not occur in rough endoplasmic reticulum ?
Cleavage of signal peptide
Protein glycosilation
Protein folding
Phospholipid synthesis
As we learnt in
RER and SER -
The endoplasmic reticulum bearing ribosomes on their surface is called rough endoplasmic reticulum (RER), in the absence of ribosomes, they appear smooth and are called smooth endoplasmic reticulum (SER).
- wherein
Phospholipid synthesis does not take place in RER. Smooth endoplasmic reticulum are involved in lipid synthesis.
Option 1)
Cleavage of signal peptide
This is incorrect.
Option 2)
Protein glycosilation
This is incorrect.
Option 3)
Protein folding
This is incorrect.
Option 4)
Phospholipid synthesis
This is correct.
