What is the function of ATP in muscle contraction?
to what does it attach to?

[Future MD | DM erutuF]

It attaches to the myosin head to detach the cross bridge between it and the actin filament. Lack of ATP results in the inability to relax the muscle resulting in rigor mortis.

correct?

[us_doctor]

Detachment of myosin head from the myosin attachment site on actin.

^ correct. Detachment, think rigor mortis
