Why are lysosomes known as ‘suicide-bags’ of a cell?
Answer :
Lysosomes are rich in hydrolytic enzymes like (lipase, Proteases, Carbohydras, nucleases) capable of digesting organic molecule.
How different organic molecules are broken in lysosomes:
Fats ---- (lipases) ---- Glycerides
Protein ---- (Proteases) ---- Peptones + Peptides
Carbohydrates ---- (Carbohydras) ---- Disaccharides + Monosaccharides
DNA/RNA ---- (Nucleases) ---- Nucleotides
Lysosomes help in digestion but in extreme starvation situation lysosomes release hydrolytic enzymes into cell digesting the cell constituents, and eventually killing the cell. That is the reason they are called as suicidal bags.
