Correct Answer: D
Solution :
Sarcomere is the portion of myofibril that lies between two successive Z-disc. When the muscle fibre is contracted the length of the sarcomere is about 2 micrometer. At this length the actin filaments completely overlap the myosin filament. At this length the muscle is capable of generating its greatest force of contraction.You need to login to perform this action.
