Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Myofibrils**: Myofibrils are the basic rod-like units of a muscle cell and are responsible for muscle contraction. They are composed of repeating units called sarcomeres. 2. **Identifying Striated Appearance**: The striated appearance of skeletal muscles is due to the arrangement of myofibrils. This appearance is characterized by alternating light and dark bands. 3. **Recognizing the Proteins Involved**: The striated appearance is primarily due to two types of protein filaments: - **Thick Filaments**: These are primarily composed of the protein **myosin**. - **Thin Filaments**: These are primarily composed of the protein **actin**. 4. **Conclusion**: The two important proteins that contribute to the striated appearance in myofibrils are **myosin** and **actin**. ---
