Iron storing protein found in animal tissues is

Options

A. Myoglobin
B. Ferritin
C. `beta`-Globulin
D. Casein

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the iron-storing protein found in animal tissues. We need to identify the correct protein from the given options.

2. **Analyzing the Options**:
- **Option A: Myoglobin**: Myoglobin is a protein that is found in muscle tissue and is responsible for oxygen storage. While it contains heme, which binds oxygen, it does not store iron. Therefore, this option is incorrect.

- **Option B: Ferritin**: Ferritin is a protein that stores iron in the body. It is found in various tissues, including the liver and spleen, and plays a crucial role in iron metabolism. This option is correct.

- **Option C: Beta Globulin**: Beta globulin is a type of globulin protein involved in immune responses and transport of various substances in the blood. It does not have a role in iron storage, making this option incorrect.

- **Option D: Casein**: Casein is a milk protein primarily involved in nutrient transport and does not store iron. Thus, this option is also incorrect.

3. **Conclusion**: After analyzing all the options, the correct answer is **Option B: Ferritin**, as it is the protein responsible for storing iron in animal tissues.

**Final Answer**: Ferritin
