The correct Answer is:
To solve the question "Which of the following is distributed at regular intervals on the tropomyosin?", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Tropomyosin**: - Tropomyosin is a protein that runs along the length of actin filaments in muscle fibers. It plays a crucial role in muscle contraction by regulating the interaction between actin and myosin. 2. **Identifying Associated Proteins**: - Along with tropomyosin, there are other proteins that interact with actin filaments. One important protein is troponin, which is a complex of three subunits. 3. **Role of Troponin**: - Troponin is distributed at regular intervals along the tropomyosin. It consists of three components: troponin C (which binds calcium), troponin I (which inhibits actin-myosin interaction), and troponin T (which binds to tropomyosin). 4. **Conclusion**: - Based on the information, the protein that is distributed at regular intervals on the tropomyosin is **troponin**. 5. **Final Answer**: - Therefore, the correct answer to the question is **troponin**.
