Select all the true statements Each myosin head has a binding site for actin and ATP The tad of the myosin molecule acts as a molecular lever The myosin-action reaction cycle is powered by ATP hydrolysis During muscle contraction, thick and thin filaments slide past each other causing an overall lengthening of the muscle The interaction between myosin and actin converts chemical energy to mechanical work In a muscle cell. actin filaments that bind to head domains of myosin are called thin ...
