E)the plasma membrane

Question

Quizplus · Accepted Answer

The primary sorting compartment along the biosynthetic pathway is the trans-Golgi network (TGN), where proteins and lipids are sorted and packaged into vesicles for delivery to their final destination. The cis-Golgi network (CGN) is where newly synthesized proteins enter the Golgi apparatus, and the rough endoplasmic reticulum (RER) is where proteins are synthesized and processed, but neither of these compartments are the primary sorting compartment. Lysosomes are involved in the degradation of cellular waste and the recycling of cellular components, and the plasma membrane is the final destination for some proteins but not the primary sorting compartment.
