The tropomyosin filament would not be dislodged preventing contraction.

The cross bridges would remain linked and therefore contraction would stop

The cross bridges would break apart due to the presence of calcium ions enabling some contraction

The myosin heads would separate from the actin molecule due to the release of ADP that was previously present.

1. ATP hydrolysis

2. Detachment of myosin head from actin

3. Power stroke

4. Crossbridge formation
