Question

The function of lysosomes in cells is:

1. A. Protein synthesis
2. B. Intracellular digestion (Correct answer)
3. C. Energy production
4. D. Genetic information storage

Correct Answer

Option B — Intracellular digestion

Detailed Solution & Explanation

The correct answer is Intracellular digestion.

Key Points

• Lysosomes are membrane-bound vesicles carrying hydrolytic enzymes that break down proteins, lipids, carbohydrates and nucleic acids.
• Their role is intracellular digestion — digesting food particles taken in by the cell and clearing worn-out organelles.

Additional Information

• They are nicknamed the suicidal bags of the cell: if the membrane ruptures the enzymes digest the cell itself, a process called autolysis.
• Their enzymes work best in an acidic interior (pH ≈ 5), maintained by proton pumps in the membrane.
• Keep the organelle functions distinct: ribosomes for protein synthesis, mitochondria for ATP, the nucleus for genetic information and the Golgi apparatus for packaging — the three distractors here.
