Role of myosin
Did you know?
WebAt a binding location on the globular actin protein, myosin binds to actin. When myosin binds to ATP, it releases actin, allowing actin and myosin to separate. The energy from this separation is used to convert adenosine diphosphate (ADP) into adenosine triphosphate (ATP). This process of converting ADP into ATP is called oxidative phosphorylation. WebMyosin filaments play two key roles in muscle contraction and cell motility. What structure consists of myosin quizlet? Myofibrils are composed of thick (myosin) and thin (actin) …
