Glycogenolysis involves

Options

A. Oxidation of sugar
B. Conversion of glycogen into glucose
C. Conversion of glucose into glycogen
D. Conversion of glycogen into fat

Answer

**Step-by-Step Solution:**

1. **Understanding Glycogenolysis**: Glycogenolysis is a metabolic process that involves the breakdown of glycogen, which is a stored form of glucose in the body.

2. **Identifying the Role of Glycogen**: Glycogen is primarily stored in the liver and muscle cells. It serves as a readily available source of energy.

3. **The Process of Glycogenolysis**: During glycogenolysis, glycogen is converted into glucose. This process is crucial for providing immediate energy to the body, especially during periods of fasting or intense physical activity.

4. **Evaluating the Options**:
- **Oxidation of Sugar**: This is not correct as glycogenolysis specifically refers to the breakdown of glycogen, not the oxidation of glucose.
- **Conversion of Glycogen into Glucose**: This is the correct definition of glycogenolysis.
- **Conversion of Glucose into Glycogen**: This describes glycogenesis, which is the opposite process.
- **Conversion of Glycogen into Fat**: This is not part of glycogenolysis; it refers to a different metabolic pathway.

5. **Conclusion**: Based on the understanding of glycogenolysis, the correct answer is that it involves the conversion of glycogen into glucose.

**Final Answer**: Glycogenolysis involves the conversion of glycogen into glucose.
