Oxygen transporting protein is haemoglobin. Which one is oxygen storing protein

Options

A. Myoglobin
B. Actin
C. Myosin
D. Caseinogen.

Answer

To answer the question regarding which protein serves as an oxygen-storing protein, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Question**: The question asks for the oxygen-storing protein, given that hemoglobin is the oxygen-transporting protein.

2. **Review the Options**: The options provided are:
- A) Myoglobin
- B) Eptin
- C) Myosin
- D) Casinogen

3. **Analyze Each Option**:
- **Casinogen**: This is a protein found in milk and does not play a role in oxygen storage. Therefore, it can be eliminated.
- **Myosin**: This is a protein that forms filaments in muscle and is involved in muscle contraction, not oxygen storage. Thus, it can also be eliminated.
- **Actin**: Although not listed in the options, it is another muscle protein involved in contraction and does not store oxygen.
- **Eptin**: This option does not correspond to a known protein related to oxygen storage or transport, so it can be eliminated as well.

4. **Identify the Correct Answer**: The only remaining option is **Myoglobin**. Myoglobin is known to store oxygen in muscle tissues, particularly in red muscle fibers, making it the correct answer.

5. **Conclusion**: Therefore, the oxygen-storing protein is **Myoglobin**.

### Final Answer:
The oxygen-storing protein is **Myoglobin**.
