Verified step by step guidance1
Identify the main functions of each organelle listed in the problem: Nucleus, Rough endoplasmic reticulum, Golgi apparatus, and Mitochondrion.
Recall that the nucleus primarily stores genetic information and controls cellular activities, but does not modify or package proteins.
Understand that the rough endoplasmic reticulum (RER) is involved in the synthesis of proteins, especially those destined for secretion or membranes, but it does not perform the final modification or packaging.
Recognize that the Golgi apparatus receives proteins from the RER, modifies them (such as adding carbohydrate groups), sorts them, and packages them into vesicles for delivery to their correct cellular destinations.
Note that mitochondria are responsible for energy production through cellular respiration and are not involved in protein modification or packaging.
