Answer Key : (a) -

(a)

Cross-bridge ditachment.

When ATP binds to myosin filament there is a detachment of myosin and actin filament. Due to detachment, the sliding (contraction) takes place and the hydrolysis of ATP to ADP takes place. In that step again, the cross bridge formation between actin and myosin takes place
