Yes
ATP allows actin and myosin filaments to release from each other during muscle contraction by assisting in the detachment of the myosin heads from actin. It also helps in resetting the myosin heads for the next contraction cycle by providing energy for the process of cross-bridge formation.
When ATP binds to myosin, it causes myosin to release actin, allowing for muscle relaxation. The energy stored in ATP is used to detach myosin from actin and prepare the cross-bridge for another contraction cycle.

ATP not ADP binds to actin-myosin and is cleaved by to ADP.
Yes...ATP causes myosin to detach from actin. Then, Hydrolysis of ATP, which results in ADP and P, causes conformational change in myosin head to swivel or pivot about its axis and then weakly bind to an actin filament. Once the myosin head binds, a conformational change in the myosin head will cause the P to leave (the ADP is still stuck on). The leaving of the P causes the power stroke or "the pulling of the actin filament/rowing stroke". ADP then leaves and the myosin is now back at its original state.
The binding of ATP to the myosin head causes cross bridge detachment by disrupting the binding between myosin and actin. ATP provides the energy necessary for myosin to release from actin and reset for the next contraction cycle.
For attachment of myosin heads to actin, calcium ions must bind to troponin, causing tropomyosin to move out of the way, exposing the binding site on actin. ATP then binds to the myosin head, leading to its activation and attachment to actin. For detachment, ATP is hydrolyzed, causing a conformational change in the myosin head that releases it from actin.
Cross bridge detachment occurs when ATP binds to the myosin head, causing it to release from the actin filament. This process is necessary for the muscle to relax and reset for another contraction.

Actin is the molecule that has a binding site for myosin heads. This interaction is crucial for muscle contraction as myosin binds to actin and generates force to cause muscle movement.
Myosin is a molecular motor that converts ATP to energy. Actin is responsible for cell movement and uses energy from the ATP conversion done by myosin..

ATP (--> ADP+Pi) and actin
ATP
During muscle contraction, ATP is essential for the interaction between actin and myosin, as it provides the energy needed for myosin heads to bind to actin and perform the power stroke. Additionally, ATP is required for the detachment of myosin from actin, allowing the cycle to repeat. During relaxation, ATP is crucial for the active transport of calcium ions back into the sarcoplasmic reticulum, which helps to terminate the contraction and restore the muscle to its resting state. Without ATP, muscles would remain contracted and unable to relax properly.
ATP, of course. When the myosin head extends towards the actin thin filament it has in it's active site ADP and P +. So, when the stroke is over the ADP and P+ fall out and are replaced by ATP, which immediately metabolizes to ADP and P +.
