Options

A. 4
B. 6
C. 8
D. 10

Answer

To determine the number of glucose residues present in each spiral turn of glycogen, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Glycogen Structure**:
- Glycogen is a branched polymer made up of glucose units. It serves as a form of energy storage in animals.

2. **Identifying the Spiral Structure**:
- Glycogen has a helical structure, and it is important to note that it consists of both linear and branched chains of glucose.

3. **Determining the Number of Glucose Residues**:
- Each spiral turn of glycogen typically contains approximately 10 to 14 glucose residues.

4. **Selecting the Minimum Value**:
- The question asks for the number of glucose residues in each spiral turn. The minimum number is often considered for such questions, which is 10.

5. **Conclusion**:
- Therefore, the number of glucose residues present in each spiral turn of glycogen is **10**.

### Final Answer:
The number of glucose residues present in each spiral turn of glycogen is **10**.
