When myosin heads bind to actin they use chemical energy from the breakdown of atp to generate a pulling force against actin filaments, then detach and prepare to bind again
This cycle involves a series of steps where myosin heads bind to actin, pull, and then release, generating force and enabling muscle shortening.
B atp is hydrolyzed to adp and a phosphate allowing the myosin head to move towards. This action generates the force required for muscle contraction.
