|
Exposure of active sites on actin, cross bridges are formed and released , power stroke |
Events of skeletal muscle contraction |
|
|
Cross bridge cycle |
1.Release of ca2 from sarcoplasmic reticulum exposes binding sites on actin 2. Energized myosin head binds to exposes active site on actin molecule of thin filament, this forms cross bridge 3. Energy (adp+p) leaves myosin head, changing its shape, tilting in a backward direction. As it does this it pulls the actin molecule with it towards the center of the sacraments, this is power stroke 4. After power stroke, the myosin head remains attached to the actin filament until new atp molecule binds to the head and detaches it 5. The atp breaks into adp+p , energizing the myosin heads again, the reattach the myosin binding sites on the actin filament forming another cross bridge 6. Cycle repeated from #3 |
