Proteins can be modified in either the rough endoplasmic reticulum or the Golgi complex.

Question

Quizplus · Accepted Answer

Both the rough endoplasmic reticulum and the Golgi complex are involved in modifying proteins. The rough endoplasmic reticulum adds initial modifications such as signal sequences and glycosylation, while the Golgi complex adds further modifications such as additional glycosylation and sorting of proteins into different vesicles for secretion or transport to different parts of the cell.
