Question

The cell organelle which helps in the synthesis of fats in adipose tissue is

• A. smooth endoplasmic reticulum
• B. rough endoplasmic reticulum
• C. mitochondria
• D. adipocytes

Answer 1

The correct option is A

smooth endoplasmic reticulum

The correct option is A.

Explanation of the correct option :

1. Endoplasmic reticulum is a large network of fluid-filled connecting tubes.

2. It is of 2 types- rough endoplasmic reticulum and smooth endoplasmic reticulum.

3. Endoplasmic reticulum without ribosomes is called smooth endoplasmic reticulum and is mainly composed of tubules and vesicles.

4. It is mainly considered with the synthesis of lipids in the cells of adipose tissue.

Explanation of the incorrect options :

Option B :

1. The rough endoplasmic reticulum possesses ribosomes on its surface.
2. As ribosomes are present rough endoplasmic reticulum is mainly involved in protein synthesis.

Option C :

1. Mitochondria are rod-shaped structures bounded by a double-layered membrane.
2. It provides the site for cellular respiration and thereby releases energy.

Option D :

1. Adipocytes are specialized cells for the storage of fat.
2. It is also known as fat cell or lipocyte.
3. It is found mainly beneath the skin.

Final answer: The cell organelle which helps in the synthesis of fats in adipose tissue is the smooth endoplasmic reticulum.
