From the list of proteins given below, select the correct ones for muscular tissue.
A. Myosin , B. Myoglobin, C. Elastin, D. Ossein , E. Actin

Options

A. A,B,C and E
B. A,D and E
C. A, B and E
D. A,B,C,D and E

Answer

To solve the question regarding which proteins are associated with muscular tissue, we will analyze each protein listed in the options.

### Step-by-Step Solution:

1. **Identify the Proteins:**
- A. Myosin
- B. Myoglobin
- C. Elastin
- D. Ossein
- E. Actin

2. **Analyze Each Protein:**
- **Myosin (A):**
- Myosin is a motor protein that plays a crucial role in muscle contraction. It interacts with actin to facilitate muscle movement.
- **Conclusion:** Myosin is associated with muscular tissue. (Correct)

- **Myoglobin (B):**
- Myoglobin is a protein that binds oxygen in muscle cells, similar to hemoglobin in blood. It helps supply oxygen to the muscles during contraction.
- **Conclusion:** Myoglobin is associated with muscular tissue. (Correct)

- **Elastin (C):**
- Elastin is a protein that provides elasticity to tissues. It is primarily found in connective tissues, not in muscular tissue.
- **Conclusion:** Elastin is not associated with muscular tissue. (Incorrect)

- **Ossein (D):**
- Ossein is a form of collagen found in bone. It is not involved in muscle tissue.
- **Conclusion:** Ossein is not associated with muscular tissue. (Incorrect)

- **Actin (E):**
- Actin is another motor protein that works alongside myosin in muscle contraction. It is a fundamental component of the muscle fibers.
- **Conclusion:** Actin is associated with muscular tissue. (Correct)

3. **Final Selection:**
- The correct proteins associated with muscular tissue are Myosin (A), Myoglobin (B), and Actin (E).
- Therefore, the answer is: A, B, and E.
