Which of the following is NOT a part of the reaction sequence for the involvement of free actin,free myosin,and ATPase activity on each other?
A)Actin binds and activates ATPase activity by stimulating the formation of Camp.
B)In the absence of actin,the addition of ATP to myosin produces a rapid release of H⁺.
C)New ATP is bound to the actomyosin complex.
D)Actomyosin dissociates into actin and myosin.

While actin does stimulate ATPase activity, it does so by increasing the affinity of myosin for ATP, not by stimulating the formation of Camp. The other options are all part of the reaction sequence for the involvement of free actin, free myosin, and ATPase activity on each other.
