Question

Which cell organelle is called a ‘digestive bag'?

Answer 1

A membrane-bound organelle that contains hydrolytic enzymes that destroy the bacteria and the virus in the cell.

Complete step-by-step answer:
Lysosomes are the cell organelle present in the eukaryotic cells. They are membrane-bound organelle found in many animal cells. They are small, spherical-shaped vesicles inside which the hydrolytic enzymes are found that can break down various types of biomolecules.
They are called the ‘digestive bags' because they have enzymes that play a major role in cellular digestion. It will mix with a food vacuole and the enzymes in the lysosome help in digesting the food materials in the food vacuole.
Lysosomes are also called as 'suicide bags' because these are responsible for processing the nutrients and destroys the cell after cell and will be dead with themselves. It sometimes also destroys the layer of the inner stomach when food is not provided properly and it leads to ulcers.

Additional Information:
-Lysosomes are known to contain more than 60 different enzymes and have more than 50 membrane proteins.
-Enzymes of lysosomes are synthesized in the rough endoplasmic reticulum and then exported to the Golgi apparatus.
-The enzymes are trafficked from the Golgi apparatus to lysosomes in small vesicles which later fuses with larger acidic vesicles.
-The size of the lysosomes varies greatly, the larger ones can be 10 times the size of the smaller ones.

Note: Lysosomes were discovered and named by Belgian biologist Christian de Duve, who received the Nobel Prize in Physiology or Medicine in 1974. The main function of lysosomes is to act as the waste disposal system of the cell.
