At what location(s)within a cell is/are proteins glycosylated?

Question

Quizplus · Accepted Answer

Proteins are glycosylated in the endoplasmic reticulum and Golgi complex. The process begins in the endoplasmic reticulum where a core oligosaccharide is added to the protein. Then, the protein is transported to the Golgi complex where further modifications occur, including the addition of more diverse types of sugar molecules to the core oligosaccharide, resulting in the formation of a complex glycan chain.
