Answer:
When a cardiac muscle cell contracts, the myosin filament pulls the actin filaments toward each other, which causes the cell to shrink. The cell uses ATP to power this contraction. A single myosin filament connects to two actin filaments on either side. This forms a single unit of muscle tissue, called a sarcomere.
