Which specific organelle is referred to as the 'suicide bag' of the cell due to the presence of hydrolytic enzymes?
Lysosome
Mitochondria
Ribosome
Golgi apparatus
Lysosome
Lysosomes are membrane-bound organelles containing powerful hydrolytic (digestive) enzymes capable of breaking down all major biological macromolecules. When a cell is damaged, diseased, or undergoing programmed cell death, lysosomes may burst and digest the entire cell, earning them the nickname 'suicide bags'.
Lysosomes are membrane-bound organelles containing powerful hydrolytic (digestive) enzymes capable of breaking down all major biological macromolecules. When a cell is damaged, diseased, or undergoing programmed cell death, lysosomes may burst and digest the entire cell, earning them the nickname 'suicide bags'.
Think of lysosomes like a self-destruct mechanism or a demolition crew inside a building; if the structure is completely compromised, they trigger a controlled shutdown.
L for Lysosome = 'Little demolition bags that Leave nothing behind'.
pHтЙИ4.5тИТ5.0 тАФ Optimal acidic internal environment for lysosomal hydrolytic enzymes
Lysosomes maintain an acidic internal environment optimal for the activity of their acid hydrolases, protecting the rest of the cell from accidental damage. When triggered by stress or apoptosis, the lysosomal membrane ruptures, releasing these enzymes into the cytoplasm to systematically dismantle cellular components.
Discovered by Christian de Duve in 1949.
Contain over 60 different types of hydrolytic enzymes including proteases, lipases, and nucleases.
Play a critical role in autophagy, phagocytosis, and apoptosis (programmed cell death).
Efficient cellular waste clearance and recycling
Protection against invading pathogens via phagocytosis
Uncontrolled rupture of lysosomes causes cellular damage and contributes to certain pathological conditions.
Intracellular digestion and waste removal
Amphibian metamorphosis (e.g., tail resorption in tadpoles)
Mitochondria are termed the powerhouse of the cell due to ATP generation.
Ribosomes are non-membrane-bound structures responsible for protein synthesis.
Golgi apparatus modifies, sorts, and packages proteins and lipids.
A is correct тАФ Lysosomes are termed the suicide bags of the cell because they contain hydrolytic enzymes that can digest the entire cell upon rupture.
RRB exams frequently test cell organelle nicknames; make sure to memorize mitochondria as the powerhouse, ribosomes as protein factories, and lysosomes as suicide bags.
