E) Golgi apparatus

Question

Quizplus · Accepted Answer

The rough endoplasmic reticulum (rER) is the site of protein synthesis and processing in eukaryotic cells. The partially translated polypeptides are found in the lumen of the rER, where they undergo processing before being transported to the Golgi apparatus for further modification and sorting. Mitochondria, nucleus, and peroxisomes do not have a role in protein processing.
