Sort the following events to show the sequence in the mechanochemical cycle of myosin II, following ATP binding by the head domain. Your answer would be a four-digit number composed of digits 1 to 4 only, e.g. 1342.
(A) Myosin head binds tightly to actin.
(B) Power stroke is triggered.
(C) Cocking occurs and the head is displaced along the actin filament.
(D) The binding affinity of myosin for actin is reduced.
