Which organelle is known as the 'suicide bag' of the cell?
Mitochondria
Lysosome
Ribosome
Golgi Apparatus
Lysosome
Lysosomes are membrane-bound organelles containing powerful hydrolytic enzymes that break down cellular waste and foreign matter. When a cell becomes damaged or undergoes programmed cell death, lysosomes burst and digest the cell entirely, earning them the nickname 'suicide bags' of the cell.
Lysosomes are membrane-bound organelles containing powerful hydrolytic enzymes that break down cellular waste and foreign matter. When a cell becomes damaged or undergoes programmed cell death, lysosomes burst and digest the cell entirely, earning them the nickname 'suicide bags' of the cell.
Think of a safety mechanism in a secure facility that triggers a complete self-neutralization protocol if the building suffers catastrophic failure.
L for Lysosome, L for Lytic destruction
Lysosomes maintain an acidic interior environment (pH┬а4.5тИТ5.0) optimal for acid hydrolases. When cell damage occurs, the lysosomal membrane ruptures, releasing these enzymes into the cytoplasm to degrade cellular macromolecules, resulting in autolysis.
Lysosomes are single membrane-bound vesicles produced by the Golgi apparatus.
They contain acid hydrolases active in acidic conditions.
Responsible for intracellular digestion and autolysis.
Removes worn-out cell parts and foreign invaders
Plays a crucial role in embryonic development via programmed cell death
Uncontrolled rupture can cause widespread tissue damage and cell death
Removal of webbed tissues during human embryonic development
Defense mechanism in white blood cells against invading pathogens
Discovered by Christian de Duve in 1949.
Option A is Mitochondria (powerhouse), Option C is Ribosome (protein synthesis), and Option D is Golgi Apparatus (packaging and secretion).
B is correct тАФ Lysosome is known as the 'suicide bag' of the cell because its hydrolytic enzymes can digest the entire cell upon membrane rupture.
Focus on matching each organelle with its primary biological nickname (e.g., powerhouse, suicide bag, protein factory) for rapid scoring in competitive exams like RRB JE.
