- Sliding Filament Mechanism
- Action Potential travels to Sarcoplasm
- Starting
- Sarcoplasmic Reticulum actively transported Ca2+ in
- Action potential causes Ca2+ to diffuse into sarcoplasm
- Ca2+ cause tropomyosin molecules to pull away from myosin binding site
- ADP on myosin head binds to actin filament, forms a cross-bridge
- Myosin head change their angle, pulling actin filament, releasing ADP
- ATP binds to myosin head, causing it to detach from actin
- Ca2+ activate ATPase. ATP forms ADP+Pi+E.
- This energy is used to return myosin head to original position
- Ca2+ activate ATPase. ATP forms ADP+Pi+E.
- ATP binds to myosin head, causing it to detach from actin
- Myosin head change their angle, pulling actin filament, releasing ADP
- ADP on myosin head binds to actin filament, forms a cross-bridge
