Answer:
Myosin heads are attached to actin filaments
Explanation:
During the process of muscle contraction, myosin heads are attached to actin filaments. ATP is necessary for their release and for the muscle relaxation.
In rigor mortis, myosin heads continue binding with the active sites of actin proteins. This occurs because after death, there is no production of ATP and consequently, the muscle is unable to relax until further enzyme activity degrades the complex.
