Why are lysosomes known as suicidal bags

Q. Lysosomes are known as suicidal bags of cells why? Answers:- They contain digestive enzymes, lysosomes are known as cell suicide bags. Organelles are lysosomes. To explain the Lysosomes, Christian de Duve coined the term “suicidal bags of cell.” The lysosomes release digestive enzymes that digest all cells if something bursts. Cells die as a result of this. As a result, Lysosomes are known as “cell suicide bags.” Lysosomes are a type of cell organelle that is very small. They are found in eukaryotic or nucleus-bearing cells. Additionally, they can be found in the cytosol of cells. Those that float around outside the nucleus of the cell. The importance of lysosome function in cells cannot be overstated. Lysosomes are sphere-shaped sacs that contain hydrolytic enzymes that can break down a wide range of biomolecules. Lysosomes are well-known organelles. Because they contain lytic enzymes capable of digesting cells and unwanted materials, they are known as cell suicide bags. When a cell is damaged, it undergoes autolysis and bursts open. The hydrolytic enzymes are released as a result of this. The enzymes that have been removed then digest their own cell, causing it to die. As a result, they’ve earned the moniker “cell suicide bags.” Lysosomes are known to contain over 60 enzymes as well as more than 50 membrane proteins. Lysosome enzymes are synthesized in the rough endoplasmic reticulum and exported to the Golgi apparatus after a complex of CLN6 and CLN8 proteins recruit...

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.

Lysosomes are organelles that were initially thought to serve the function of dissolving cells when those cells were about to die. The enzymes within lysosomes would burst out of it, dissolving cells from within. The term was invented decades ago, prior to the discovery of their other cellular-sustaining properties. Lysosomes get their name from the word " lysis" which refers to the decomposition of cells. Lysosomes are responsible for digesting foreign particles that enter the cell through a process known as autolysis, which is divided into heterophagy and autophagy. Heterophagy is when lysosomes digest foreign particles; autophagy is when lysosomes release digestive enzymes to dissolve the cell itself. This is done when a cell is damaged or parts of the cell no longer function. So, yes, lysosomes do bring about the end of a cell, but only when a cell can no longer function or is damaged. The term "suicide bag" sticks probably because it is hard to forget. See eNotes Ad-Free

Lysosomes: • These are sphere-shaped sacs inside the cell. • Their main function is cellular digestion and waste removal. • These are filled with hydrolytic enzymes. • The hydrolytic enzymes have lytic action. • These enzymes digest cells, pathogens, and unwanted waste materials. • These cells autolyze and burst while opening. • They released content that is capable of damaging the entire cell. • Hence, lysosomes are called suicidal bags of cells.
