Only myosine is present in_____________?
Correct answer: C. H zone
- A. A band
- B. 1 band
- C. H zone
- D. Sarcomere
Explanation
The H zone is the central part of the sarcomere containing thick myosin filaments without overlapping thin actin filaments, so only myosin is present there. Students may choose the A band because it contains myosin, but the A band also includes regions where actin overlaps myosin.
