Muscle contraction results from the repeated cycle of interactions between myosin and actin. What is the last step of this cycle, after which the cycle starts over again?
A) New ATP molecules bind to the myosin heads, causing them to disengage from the actin.
B) Myosin heads extend toward the Z lines at the ends of the sarcomere.
C) The myosin heads split the ATP into ADP and Pi and store the energy.
D) The myosin head bends (the power stroke).
