During prolonged starvation, body derives nutrition from storage of-

Options

A. Liver and adipose tissue
B. Spleen
C. Liver and lungs
D. Subcutaneous fat and Pancreas

Answer

**Step-by-Step Solution:**

1. **Understanding Prolonged Starvation**: During prolonged starvation, the body needs to derive energy and nutrition from its internal reserves since external food intake is absent.

2. **Identifying Nutritional Reserves**: The body has various storage forms of nutrients, primarily glycogen and fat. Glycogen is stored in the liver and muscles, while fat is stored in adipose tissue.

3. **Role of Glycogen**: Glycogen is a polysaccharide that serves as a major carbohydrate reserve in the body. It is primarily stored in the liver and skeletal muscles. When the body is in a state of starvation, the glycogen stores begin to deplete.

4. **Glycogen Breakdown**: As the glucose levels in the blood decrease due to lack of food intake, the body initiates the breakdown of glycogen into glucose. This process is known as glycogenolysis.

5. **Role of Adipose Tissue**: In addition to glycogen, the body also relies on fat stored in adipose tissue. During starvation, fat can be broken down into fatty acids and glycerol, which can be converted into glucose or used directly for energy (ATP production).

6. **Conclusion**: Therefore, during prolonged starvation, the body derives its nutrition from the storage of glycogen in the liver and fat in adipose tissue.

7. **Final Answer**: The correct answer is option 1: "During prolonged starvation, the body derives its nutrition from storage in the liver and adipose tissue."
