how lysosomes are suicidal bags?
4676
Lysosomes are known as suicide bags of the cell because they contain lytic enzymes capable of digesting cells and unwanted materials. When lysosomes burst, the lytic enzymes within the organelle spill all over the cell, rupturing the cell membrane or cell wall and inducing the death of the cell.

Mitochondria packages energy from food while lysosome eats up the ill-functioning organelles or the whole cell.

Arguably, lysosomes are vesicles that can store mature lysosomal enzymes and deliver them to a late endosomal compartment when needed. The resulting organelle is called the hybrid organelle or endolysosome. Lysosomes bud off the hybrid organelle in a process referred to as lysosome re-formation (Bright et al. 1997).

A lysosome has three main functions: the breakdown/digestion of macromolecules (carbohydrates, lipids, proteins, and nucleic acids), cell membrane repairs, and responses against foreign substances such as bacteria, viruses and other antigens.

Yellow clinical waste bags are used in the UK to safely dispose of clinical waste produced by animals or humans. Bags need to comply with the UN3291 standard and conform to European legislation to mitigate any potential risks.

centrioles and lysosomes are present in animal cells but not in plant cells.

Cancer cells and infected cells often lose their MHC I, leaving them vulnerable to NK cell killing. Once the decision is made to kill, the NK cell releases cytotoxic granules containing perforin and granzymes, which leads to lysis of the target cell.

Lysosome. ... Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.

During endocytosis, the plasma membrane of the cell forms a pocket around the material to be internalized. The pocket closes and then separates from the plasma membrane. In phagocytosis, a type of endocytosis, large vesicles ingest whole microorganisms.

Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars.

The lysosomes contain hydrolytic enzymes which are capable of breaking down organic matter in case of any disturbance in cellular metabolism. For example, when a cell gets damaged, then lysosomes burst and enzymes digest their own cell. Hence, the lysosomes are known as 'suicide bags' of cell.

The main difference between endosome and lysosome is that the endosome is a vacuole which surrounds materials internalized during endocytosis, whereas the lysosome is a vacuole which contains hydrolytic enzymes. Furthermore, endosome forms at the transmembrane of the Golgi apparatus and at the plasma membrane.

The lysosomes are the animal cell's “garbage disposal”, while in plant cells the same function takes place in vacuoles. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells. The lysosomes are the animal cell's “garbage disposal”, while in plant cells the same function takes place in vacuoles.

In multicellular organisms, cells that are no longer needed or are a threat to the organism are destroyed by a tightly regulated cell suicide process known as programmed cell death, or apoptosis.

The correct answer is B) Mitochondria. Lysosomes are the cell organelles that have digestive enzymes present within its membrane.
