Question

Quizplus · Accepted Answer

The unitary displacement of the myosin refers to how far along the actin filament the myosin can move in one cycle of its interaction (or cross-bridge cycle) with actin. It is dependent on the size and structure of the myosin molecule and can vary among different types of myosin. It is not related to the number of actins displaced, the time it takes for one cycle to occur, or the duration of the myosin-actin binding.
