Why are lysosomes known as suicide bags

Hint: The lysosomal vesicles have an internal pH value of 4-5 and are filled with digestive enzymes. They are also known as a scavenger of the cell. Lysosomes were discovered by Christian de Duve. Complete answer: The lysosomes are known as suicidal bags or recycling centers or scavengers of cells because of the following properties: -The lysosomal vesicles contain almost 40 different types of hydrolases, for example, lipases, carbohydrases, proteases, etc. These digestive enzymes help digestion of cellular debris. -The pH inside lysosomal vesicles is very acidic and this pH is maintained by the proton pumps present in the lysosomal membrane. -In case any damage occurs to the cells and it is unable to properly function the lysosomal vacuoles digest the cell from inside out. This is known as autophagy. The cell component itself destroys the cells or causes self-death, this is why they are called suicidal bags. Additional Information: -Primary lysosomes: These are the first formed or newest lysosomes. They are synthesized by the Golgi apparatus. The GERL system is involved in its synthesis. -Secondary Lysosomes: When a primary lysosome fuses with a food vacuole it forms a secondary lysosome or phagolysosome. -Tertiary Lysosome: The phagolysosome after it has digested the food present inside it is referred to as the tertiary lysosome or residual bodies. They help in exocytosis of undigested substances. -Autophagosome: This type of lysosomes is formed when several primary lyso...

Hint: Lysosomes are cell organelles found in almost all cells. They consist of digestive enzymes that break down various materials in the cell. Complete answer A lysosome is a membrane-bound organelle that is found in many animal cells. They are composed of spherical vesicles that contain hydrolytic enzymes or lytic enzymes whose function is to break down various kinds of biomolecules. These hydrolytic enzymes have the capability of digesting cells and unwanted materials. During unfavorable conditions, when the lysosome bursts, the lytic enzymes within the organelle splits up all over the cell, this leads to the rupturing of the cell membrane or cell wall and thus resulting in the death of the cell. The lysosome will kill the organelle by its enzymes if it is damaged, and if the whole cell is damaged, then the lysosome will kill it by its enzymes, even itself. Because of this reason lysosomes are known as the suicidal bags of the cell. Lysosomes act as the waste disposal mechanism of the cell by digesting unwanted materials in the cytoplasm. They are known to contain more than 600 different enzymes. These enzymes are synthesized in the rough endoplasmic reticulum and are then transported to the Golgi apparatus. These enzymes are then passed from the Golgi body to the lysosomes in small vesicles, which later fuse to form larger acidic vesicles. Note: Lysosomes were discovered and named by Belgian biologist Christian de Duve. He later received the Nobel Prize in Physiology o...

Lysosomes are cellular organelles which produce digestive enzymes that play a role in the breakdown of waste materials, cellular debris as well as foreign particles. In case of any dysregulation in cellular metabolism, these lysozymes release their digestive enzymes which digest or kills its own cell. Hence, lysosomes are known as 'suicide bags' of a cell.
