Hello! i really need help with this last question. thanks!

Put the following events of the sliding filament mechanism (and only that sliding filament mechanism) in the correct order, starting with a cell where sarcoplasmic calcium levels have just risen. Not all steps will be used, not all steps are included. (/4 point each) a) actin is pulled toward M line b) actomyosin complex dissociates c) actotitin complex is formed d) ADPP, are joined to form ATP e) ADP P, dissociate from actomyosin f ATP binds to the cross bridge/myosin head g) calcium binds tropomyosin h) calcium binds troponin i) DHP receptors are activated j)myosin binding sites available k) myosin filaments dissociate I) power stroke pushes myosin toward the M line -Event #1 · Event #2 · Event #3 . Event #4 Event #5 Event #6 .

Explanation / Answer

1. Ca binds Troponin.

2. Actomyosin complex dissociates.

3. Myosin binding sites become available.

4. AFP+Pi are joined to form ATP

5. ATP binds to cross bridges/myosin head.

6. Power stroke pushes the myosin head towards M line.
