Find the statement which is INCORRECT about brown adipose tissue.

Options

A. It is reddish-brown in colour due to more myoglobin.
B. It is present in developing foetus and newborn .
C. It is a good insulator and major source of energy reserve .
D. It is a type of loose connective tissue .

Answer

To find the incorrect statement about brown adipose tissue, let's analyze the provided options step by step.

### Step 1: Understand what brown adipose tissue is
Brown adipose tissue (BAT) is a type of fat tissue that is primarily involved in thermogenesis (heat production) and energy metabolism. It is characterized by a higher number of mitochondria and a rich blood supply, which gives it a reddish-brown color.

**Hint:** Remember that brown adipose tissue is involved in heat production and has a unique color due to its cellular composition.

### Step 2: Analyze the options
1. **It is reddish brown in color due to more myoglobin.**
- This statement is incorrect. The reddish-brown color of brown adipose tissue is primarily due to the presence of iron in the mitochondria, not myoglobin, which is found in muscle tissue.

**Hint:** Focus on the reason behind the color of brown adipose tissue; it’s linked to iron, not myoglobin.

2. **It is present in developing fetus and newborn.**
- This statement is correct. Brown adipose tissue is indeed present in fetuses and newborns, providing insulation and helping to maintain body temperature.

**Hint:** Consider the role of brown adipose tissue in thermoregulation for developing organisms.

3. **It is a good insulator and major source of energy reserve.**
- This statement is also correct. Brown adipose tissue serves as an insulator and is involved in energy metabolism.

**Hint:** Think about how brown adipose tissue functions in energy storage and heat retention.

4. **It is a type of loose connective tissue.**
- This statement is correct as well. Brown adipose tissue is classified as a loose connective tissue due to its structure and the spaces between cells.

**Hint:** Recall the structural characteristics of connective tissues and how they relate to insulation.

### Conclusion
The incorrect statement about brown adipose tissue is the first one: "It is reddish brown in color due to more myoglobin."

**Final Answer:** The first option is incorrect.
