Which cell organelle is known as the 'suicide bag' of the cell?
Mitochondria
Lysosome
Ribosome
Golgi apparatus
Lysosome
Lysosomes are membrane-bound organelles containing hydrolytic enzymes that break down cellular waste and macromolecules. When a cell is damaged, diseased, or undergoing programmed cell death, these organelles rupture and digest the entire cell, earning them the designation 'suicide bags'.

Like an automated self-destruct or internal demolition charge designed to dismantle a compromised facility.

pH=тИТlog10тАЛ[H+] тАФ metric defining the acidic interior environment
Proton pumps maintain an acidic internal pH of 4.5тАУ5.0 inside a single lipid bilayer membrane. Acid hydrolases function optimally at this low pH, preventing accidental cytosolic degradation while ensuring rapid autolysis when membrane integrity fails.
Single-membrane organelle discovered by Christian de Duve.
Contains acid hydrolases (proteases, lipases, nucleases, carbohydrases).
Involved in autophagy, phagocytosis, and autolysis.
Efficient clearance of cellular debris and intracellular pathogen defense.
Uncontrolled widespread rupture causes autolysis, leading to cell death and tissue damage.
Tail resorption during amphibian (tadpole) metamorphosis.
Removal of damaged or senescent cellular organelles via autophagy.
Option A (Mitochondria) is the powerhouse of the cell generating ATP via oxidative phosphorylation.
Option C (Ribosome) is the site of protein synthesis (translation).
Option D (Golgi apparatus) modifies, sorts, and packages proteins and lipids.
B is correct тАФ Lysosomes contain hydrolytic enzymes that can digest the entire cell upon rupture, earning the title 'suicide bags'.
Classify organelles by membrane architecture for RRB/SSC exams: double-membrane (mitochondria, chloroplast, nucleus) vs single-membrane (lysosome, Golgi apparatus, ER, vacuole).
