The organ in human body where glycogenolysis takes place ?

Options

A. Large intestine
B. Liver
C. Small Intestine
D. Kidney

Answer

**Step-by-Step Solution:**

1. **Understanding Glycogenolysis:**
- Glycogenolysis is the biochemical process where glycogen, a stored form of glucose, is broken down into glucose molecules. This process is crucial for maintaining blood glucose levels, especially during fasting or intense exercise.

2. **Identifying the Organ:**
- The primary organ responsible for glycogenolysis is the liver. The liver plays a central role in carbohydrate metabolism, including the conversion of glycogen to glucose when blood glucose levels decrease.

3. **Considering Other Options:**
- **Large Intestine:** This organ is primarily involved in water absorption and the formation of feces. It does not play a role in glycogenolysis.
- **Small Intestine:** This organ is mainly responsible for digestion and nutrient absorption, not for glycogenolysis.
- **Kidney:** While the kidneys have various metabolic functions, they are not the primary site for glycogenolysis.

4. **Conclusion:**
- Based on the information and analysis of the options, the correct answer is the liver, as it is the organ where glycogenolysis primarily occurs.

**Final Answer:**
The organ in the human body where glycogenolysis takes place is the **liver**.
