Question

What part of the cell does serve to process, package and export proteins?

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

Answer 1

The correct option is D

Golgi apparatus

The correct option is D.

Explanation of the correct option:

1. The Golgi apparatus is found in most cells.
2. It was named after Camillo Golgi.
3. They are found in the cytoplasm of both, plant and animal cells.
4. It is composed of stacks of membrane-bound structures known as cisternae.
5. Golgi apparatus produces numerous vesicles which involve the storage and transportation of lipids, proteins, and other particles from one organelle to another.
6. Some vesicles are modified to form lysosomes which contain a hydrolytic enzyme for digestion of foreign particles.
7. It involves the formation of cell plating for the cell division in plants.

Explanation of the incorrect options:

Option A:

1. Mitochondria are the cell organelles that generate electricity or power for the cell to perform functions.
2. Power is in the form of energy or ATP.

Option B:

1. The endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.
2. As ER are of two types, Rough endoplasmic reticulum, and Smooth endoplasmic reticulum.
3. The rough endoplasmic reticulum synthesizes protein as it has ribosomes on its surface, and the smooth endoplasmic reticulum synthesizes phospholipids.

Option C:

1. Nucleolus is found inside the nucleus.
2. The main function of the nucleolus is to produce and assemble the subunits that form the ribosomes.

Final answer: Golgi apparatus serve to process, package, and export proteins.
