Muscle contraction results from an attachmentâdetachment cycle between the myosin heads extending from myosin filaments and the sites on actin filaments. The myosin head first attaches to actin together with the products of ATP hydrolysis, performs a power stroke associated with release of hydrolysis products, and detaches from actin upon binding with new ATP. The detached myosin head then hydrolyses ATP, and performs a recovery stroke to restore its initial position.
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 ...
