In the operational model for movement of myosin along an actin filament,the power stroke occurs during:
A)binding of ATP.
B)hydrolysis of ATP.
C)release of phosphate (Pi).
D)release of ADP.

Question

Quizplus · Accepted Answer

The power stroke in the movement of myosin along an actin filament occurs during the release of inorganic phosphate (Pi) from the myosin head. This event triggers the conformational change in myosin that generates the force to move it along the actin filament.
