Best Answer

The crossbridge cycle is the cyclical formation of links between actin and myosin. This results in the sliding of thin filaments towards the M line of a sarcomere. The myosin head undergoes conformation changes which allows it to swivel back and forth. In its low energy form, myosin has a low affinity for actin. The ATP prepares myosin for binding with actin by moving it to its high energy form position. When myosin contracts, it has a high affinity for actin.
