The conformation of myosin V when strongly bound to actin has been revealed by electron microscopy 39. The authors point out that, in low concentrations of ATP, when the myosin heads both remain ...

The contraction of myosin's S1 region is called the power stroke (Figure 3). The power stroke requires the hydrolysis of ATP, which breaks a high-energy phosphate bond to release energy.

ATP is needed in the body to breakdown the actin-myosin filaments in the muscle fibers. These filaments are what contract and relax to allow for movement when a person is alive. When a person dies ...
