Which of the following events do not occur in rough endoplasmic reticulum?
Which of the following events do not occur in rough endoplasmic reticulum?
Cleavage of signal peptide
Protein glycosylation
Protein folding
Phospholipid synthesis
Solution
Phospholipid synthesis does not occur in RER. It occurs inside the smooth endoplasmic reticulum (SER). A signal peptide is a short peptide present at the N-terminus of the newly synthesised proteins, that targets them to the ER and is then cleaved off. RER synthesises proteins, modification of proteins occurs in the Golgi apparatus by glycosylation.
