In cell biology, which organelle is responsible for post-translational modification, sorting, and packaging of proteins into secretory vesicles?
Answer and explanation
Correct answer: C. Golgi apparatus
- Step 1: The Golgi apparatus modifies proteins received from the rough ER (e.g., glycosylation) and packages them for cellular targeting or export. Answer: Golgi apparatus. Why not the others: Rough ER performs initial protein folding.
