Question 1

The molecular event that occurs immediately after the power stroke is the
◦ binding of actin to the myosin.
◦ release of ADP from the myosin.
◦ binding of tropomyosin to the myosin.
◦ release of actin from the myosin head.
◦ hydrolysis of ATP by the myosin head.

Question 2

The hydrolysis of ATP causes myosin to immediately
◦ release from the actin.
◦ release ADP.
◦ rotate into a position (cocked) to bind to actin.
◦ swivel, moving the actin molecule.
◦ bind more tightly to the actin (rigor).
