Question #3
Which cell organelle is responsible for the formation of lysosomes?
A. Endoplasmic Reticulum
B. Nucleus
C. Golgi apparatus
D. Mitochondria

Correct Answer: Option C


Explanation:
Lysosomes are membrane-bound vesicles containing hydrolytic enzymes formed by the Golgi apparatus. The Golgi modifies, sorts, and packages proteins from the rough ER into vesicles; some become lysosomes. These organelles function in intracellular digestion and autophagy. Rough ER synthesizes enzymes, but the final packaging into lysosomes occurs at the Golgi. Hence, Golgi is sometimes called the 'traffic police' of the cell.
