Which organelle contains hydrolytic enzymes and is called the 'suicide bag'?
Answer and explanation
Correct answer: D. Lysosome
- Step 1: Specialized membrane-bound organelles sequester acid hydrolases capable of digesting cellular macromolecules under acidic conditions (pH around ).
- Step 2: Lysosomes contain these hydrolytic enzymes; if a cell undergoes severe irreversible damage, lysosomal rupture releases enzymes that digest the host cell from within (autolysis), earning the nickname 'suicide bags'.
- Step 3: Peroxisomes catabolize fatty acids and neutralize peroxides, while mitochondria perform cellular respiration.
Answer
Lysosome.
Why not the others: Ribosome lacks a membrane and synthesizes proteins; Peroxisome oxidizes long-chain fatty acids and decomposes hydrogen peroxide using catalase; Golgi body processes and ships macromolecules rather than performing autolytic cellular destruction.
