Which one of the following statements about lysosomes is NOT correct ?

Result
Your answer: —  Â·  Correct: B
Explanation

Lysosomes are membrane-bound organelles containing powerful digestive enzymes (hydrolases) that function as the cell's waste disposal system. Statement B is incorrect because lysosomal enzymes are specialized to break down organic macromolecules—such as proteins, lipids, carbohydrates, and nucleic acids—rather than inorganic materials.

  • Waste Disposal: They digest worn-out organelles and cellular debris, keeping the cell clean (Option A).
  • Suicidal Bags: If a cell is damaged beyond repair, lysosomes may burst and release enzymes that digest the entire cell, a process known as autolysis (Option C).
  • Foreign Material: Lysosomes play a crucial role in the immune response by engulfing and destroying foreign invaders like bacteria and viruses through phagocytosis, effectively neutralizing external threats (Option D).
