- Sliding filament theory
- Happens when actosin and myosin filaments slides passed one another
- Sarcomere shortens
- Calcium is released from the sarcoplasmic reticulum to the myofibuals
- Nerve impulse travels from brain to muscles
- Ions then bond with the troponin recepters on the actin
- Causing the actin to change shape
- Creating binding sights for the myosin to attach to the actin. Called a cross bridge
- ADP and PI leave the myosin causing myosin to contract
- Causing the ADP and PI to bind and create ATP. This pulls away the myosin away from the actin
- Then the myosin binds with the next sight
- Causing the ADP and PI to bind and create ATP. This pulls away the myosin away from the actin
