Question

------ cell organelles take part in the formation of the lysosomes.
A) Endoplasmic reticulum
B) Golgi bodies
C) Both A and B
D) Mitochondria

Answer 1

Hint: A lysosome is a membrane-bound cell organelle that is a part of the cell membrane network along with the Golgi apparatus and endoplasmic reticulum. These three are interlinked to each other to perform various activities.

Complete Answer:
- The formation of lysosomes involves both the endoplasmic reticulum and the golgi apparatus.
- Enzymes of the lysosomes are synthesized from the proteins of the rough endoplasmic reticulum.
- The enzymes are released from the Golgi apparatus in small vesicles that fuse with the acidic vesicles of the Golgi apparatus. These acidic vesicles are termed as endosomes. This fusion forms a lysosome.

So, ‘Both A And B’ is the correct answer.

Additional information: Lysosomes are spherical cell organelle, that contains the hydrolytic enzymes or digestive enzymes. They break down excess or worn-out cell parts.
- Lysosomes act as the "garbage disposal" of a cell. They also destroy and remove invading viruses and bacteria.
- Lysosomes are also called ‘suicidal bags’ as they undergo a process that is called programmed cell death or apoptosis. This happens when the repairing of the damaged cell is not possible, the digestive enzymes start digesting their cell.

Note: It seems like the Golgi apparatus is solely responsible for the formation of lysosomes. But, without enzyme lysosomes are just vesicles that can not perform specific activities such as digestion as the endoplasmic reticulum provides those enzymes.
