Question

Lysosome arises from:

• A. Endoplasmic reticulum
• B. Golgi apparatus
• C. Nucleus
• D. Mitochondria

Answer 1

The correct option is B

Golgi apparatus

The correct option is B.

Explanation for correct answer:

1. Lysosomes are tiny sacs filled with fluid-containing enzymes which enable the cell to reuse its nutrients and are also responsible for destroying the cell after it has failed.
2. A lysosome is a type of membrane-bound organelle that is present in animal cells.
3. Lysosomes have a single external membrane conforming to a phospholipid bilayer and contain acid hydrolases which are enzymes capable of breaking-down macromolecules.
4. Lysosomes arise from the Golgi apparatus. Along with the Golgi apparatus, the endoplasmic reticulum is referred to as the cell’s protein machinery.
5. In the Golgi apparatus, any protein formed in the endoplasmic reticulum is identified and from there it reaches various components of the cell.

Explanation for incorrect options:

Option A:

The endoplasmic reticulum mainly functions in the metabolism of lipid and protein synthesis.

Option C:

Nucleus stores the genetic material and controls all the activities performed by the cell.

Option D:

Mitochondria serves the function of producing energy for performing all cellular activities.

Final answer: Lysosome arises from the Golgi apparatus.
