String Filament Theory steps (ordered): –Calcium ions are released by sarcoplasmic reticulum into the sarcoplasm. –The breakdown of ATP releases energy‚ releasing the head of the myosin. –Calcium ions bind to troponin‚ exposing the binding site on the actin filament. –The myosin head attaches to the exposed binding site on the actin filament‚ forming a cross-bridge. –The flexing of the cross-bridge pulls the actin filament toward the center of the sarcomere. –An ATP molecule in the reattaches
