80% of the lactic acid is converted to _______ in the liver

Options

A. Cellulose
B. Acetyl CoA
C. Glycogen
D. Starch

Answer

**Step-by-Step Solution:**

1. **Understanding Lactic Acid Conversion**: Lactic acid is produced in the body during anaerobic respiration, particularly in muscles during intense exercise. After its production, it needs to be processed, especially in the liver.

2. **Identifying the Options**: The options provided are cellulose, acetyl coenzyme A, glycogen, and starch. We need to determine which of these lactic acid is converted into in the liver.

3. **Analyzing Each Option**:
- **Cellulose**: This is a carbohydrate that humans cannot digest. It is not utilized in the human body, so it cannot be the correct answer.
- **Acetyl Coenzyme A**: While lactic acid can be converted to pyruvate and then to acetyl coenzyme A, this is not the primary conversion that occurs in the liver for lactic acid. Therefore, this option is not the best choice.
- **Glycogen**: This is a stored form of glucose in the body, particularly in the liver and muscles. Lactic acid can be converted into glucose and subsequently stored as glycogen in the liver. This makes glycogen a strong candidate for the correct answer.
- **Starch**: This is another form of carbohydrate, but humans do not store starch. Instead, they store glucose as glycogen. Thus, starch cannot be the correct answer.

4. **Conclusion**: Based on the analysis, the correct answer is that 80% of lactic acid is converted to **glycogen** in the liver.
