Which component(s)of the 6 polypeptides that make up the thick filament contain(s)the ATPase activity?

Question

Quizplus · Accepted Answer

The ATPase activity in the thick filament is mainly attributed to the myosin heavy chains, which are the major components of the thick filament. The LC1 and LC2 are light chains that regulate the activity of the myosin molecule but do not have ATPase activity. The essential light chains are also light chains but only contribute to the stability of the myosin molecule and do not have ATPase activity.
