Myosin heads bind to actin, forming crossbridges
Myosin heads split ATP and become reoriented and energized
Myosin heads rotate toward the center of the sarcomere (power stroke)
As myosin heads bind ATP, the crossbridges detach from actin
Which of the following is the third step in the sliding filament model of muscle contraction?
Myosin heads bind to actin, forming crossbridges
Myosin heads split ATP and become reoriented and energized
Myosin heads rotate toward the center of the sarcomere (power stroke)
As myosin heads bind ATP, the crossbridges detach from actin
Which of the following is the fourth step in the sliding filament model of muscle contraction?
Myosin heads bind to actin, forming crossbridges
Myosin heads split ATP and become reoriented and energized
Myosin heads rotate toward the center of the sarcomere (power stroke)
