Which of the following events does not occur in rough endoplasmic reticulum,

A

Cleavage of signal peptide

B

Protein glycosylation

C

Protein folding

D

Phospholipid synthesis

Text Solution

Verified by Experts

The correct Answer is:
D
Phospholipid synthesis does not occur in RER. It occurs inside Smooth Endoplasmic Reticulum (SER). A signal peptide is a short peptide present at the N-terminus of the newly synthesised proteins. It targets them to the ER and is then cleaved off RER synthesises proteins. It bears enzymes for modifying polypeptides synthesised by attached ribosomes, e.g. glycosylation.
