What voltage produced maximal contraction of this muscle?
Muscle is a soft tissue which is found in most animals. They are helpful in providing movement and coordination to the body. The muscle tissues consist of muscle fibre called myofibril that are composed of actin (thin) and myosin (thick) filament. The bundle of myofibril is one unit called sarcomere. The protein myosin, has 2 heavy chains, and 2 pairs of light chains intertwined with myosin heads at the end which helps in binding to the actin. Actin is a globular protein with intertwined double strands covered by tropomyosin and consists of troponin protein. Tropomyosin inhibits the attachment between actin and myosin when the muscle is inactive. Upon contraction and relation of the muscle fibre energy is generated which produces force and motion.
