Lysosomes form via Golgi packaging of RER-synthesized enzymes Steps:

• Recall that hydrolytic enzymes are synthesized on ribosomes attached to the rough ER.
• These enzymes are transported to the Golgi body for modification and packaging.
• The Golgi body forms vesicles containing enzymes, which become lysosomes.
• Mitochondria play no role in this process.

Why C is correct:

• The Golgi body modifies and packages hydrolytic enzymes into lysosomes, as per the endomembrane system's secretory pathway.

Why the others are wrong:

• A: Rough ER synthesizes the enzymes but does not form lysosomes.
• B: Mitochondria generate ATP but are unrelated to lysosome or enzyme production.

Final answer: C
