The Force Exerted by a Muscle Cross-Bridge Depends Directly on the Strength of the Actomyosin Bond

Myosin produces force in a cyclic interaction, which involves alternate tight binding to actin and to ATP. We have investigated the energetics associated with force production by measuring the force generated by skinned muscle fibers as the strength of the actomyosin bond is changed. We varied the s...
