Which event is not associated with the interaction between actin and myosin?
A) A change in the myosin head conformation causes the head to bend.
B) ATP is formed by the interaction.
C) Myosin heads bind specific sites on actin, forming cross-bridges.
D) The actin filament moves relative to the myosin filament.
E) A change in the myosin head conformation releases actin.

ATP is not formed by the interaction between actin and myosin, but rather is required for the interaction to occur. ATP binds to the myosin head, causing a conformational change that allows it to bind to actin and form a cross-bridge. The hydrolysis of ATP then provides the energy for the myosin head to change conformation again, pulling the actin filament and causing muscle contraction.
