Lysosomes are known as "suicide bags" because they contain hydrolytic enzymes capable of breaking down various biomolecules within the cell. If the lysosome's membrane ruptures, these enzymes are released into the cytoplasm, leading to the digestion and destruction of the cell itself, a process called autolysis. This self-destruction mechanism is why lysosomes are referred to as suicide bags. They play crucial roles in digesting cellular waste, recycling cell components during autophagy, and in controlled cell death when cells are damaged or no longer needed.
