The lactic acid generated during muscle contraction in coverted to glycogen mainly in

Options

A. liver
B. muscle
C. adrenals
D. pancreas

Answer

### Step-by-Step Solution

1. **Understanding the Question**: The question asks where lactic acid, produced during muscle contraction, is converted into glycogen.

2. **Identifying the Process**: The process of converting lactic acid into glycogen is part of the Cori cycle (also known as the lactic acid cycle).

3. **Recognizing the Organs Involved**: The two primary organs involved in this conversion are the liver and skeletal muscles.

4. **Explaining the Conversion**:
- During anaerobic respiration in muscles, lactic acid is produced from pyruvate.
- This lactic acid enters the bloodstream and is transported to the liver.
- In the liver, approximately 1/5 of the lactic acid is oxidized to carbon dioxide and water, while 4/5 is converted into glycogen.

5. **Glycogen Storage and Release**:
- The glycogen formed in the liver can later be converted back into glucose, which can be released into the bloodstream and transported to muscles for energy.
- This conversion of glycogen back to glucose is known as gluconeogenesis.

6. **Conclusion**: Therefore, the lactic acid generated during muscle contraction is converted to glycogen mainly in the liver and skeletal muscles.

### Final Answer
The lactic acid generated during muscle contraction is converted to glycogen mainly in the **liver** and **skeletal muscles**.
