Describe how the thin actin filament and the myosin head of a thick filament interact during one contraction cycle by arranging the steps below in the correct order. In this case, assume the following: • ATP has just bound to a myosin head, causing the myosin head to dissociate from the thin filament in a sarcomere, . Cais bound to the regulatory protein troponin on the thin filaments so that troponin has changed shape and pulled the tropomyosin filament away from the myosin binding sites on actin. For this question, you will use each answer once and only once. Step 1: Step 2: ✓ Choose The phosphate group dissociates (is “elected”) from the myosin head. Tho ATP molecule bound to the myosin head is hydrolyzed (broken down) Into a phosphate group and an ADP molecule. The myosin head changes shape — and the affinity of the myosin head for the attached phosphate group decreases. The myosin head changes shape from the bent flexed” position to the the elongated “cocked” position ADP dissociates (is “ejected”) from the myosin head so that the myosin head is free to again bind ATP. The power stroke pulls the thin filament closer to the M-line and the sarcomere shortens, The power stroke” begins as the myosin head changes shape — from the elongated “cocked” position to the bent “flexed” position.
