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.
No, ATP does not cause the detachment of myosin from actin. ATP is used to fuel the cross-bridge cycle in muscle contraction, providing the energy needed for myosin heads to form cross-bridges with actin. Detachment of myosin from actin is facilitated by a conformational change in the myosin head when ATP is hydrolyzed.
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 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 attaches to a myosin head during muscle contraction, it provides the energy needed for the myosin head to detach from actin, allowing the muscle to relax and reset for the next contraction.
The energy to swivel the head of myosin is provided by ATP (adenosine triphosphate) molecules. ATP is hydrolyzed to ADP (adenosine diphosphate) and inorganic phosphate during the power stroke of muscle contraction, releasing energy that causes the myosin head to swivel and slide along actin filaments.

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..
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.
ATP is used to detach myosin heads and move them back to position for another "power stroke."
ATP
ATP (adenosine triphosphate) is the main substance that causes the myosin head to change shape during muscle contraction. When ATP binds to the myosin head, it energizes the myosin molecule and allows it to detach from actin, resetting the myosin head for the next contraction cycle.
The hydrolysis of ATP by myosin activates the myosin head and converts it into a high-energy state. This process releases energy that is used to power muscle contraction.
Myosin
The energy on the myosin head comes from ATP (adenosine triphosphate) molecules. When ATP is hydrolyzed, it releases energy that is used to power the movement of the myosin head during muscle contraction.
Adenosine triphosphate (ATP) is the molecule that directly supplies energy to myosin during muscle contraction. Myosin uses ATP to power the movement of actin filaments, leading to muscle contraction.
