What are actin and myosin.

During muscular contraction, the myosin head binds to the exposed active sites on actin to form a

Assertion : During muscle contraction I-band and A-band get reduced. Reason :- During contraction thin filament slides over myosin filament.

Statements A-bands of the muscle are dark and contain myosin I-band are the light bands and contain actin During muscle contraction the A-band contracts The part between the two Z-lines is called as sarcomere The central part of thin filament, not over-lapped by thick filament is called H-zone of the above statements.

In the skeletal muscle, the interaction between actin and myosin filaments is triggered by
