FIELD SONG: ATP COINS Verse: In the folded inner chamber, where the oxygen river bends, tiny carriers pass the charge and the gradient slowly spends. Chorus: ATP, ATP, small permission coin, not the self and not the goal, but the work it lets us join. Verse: Glucose enters, carbon leaves, water signs the page. Energy is not a throne; it is labor in a cage. Chorus: ATP, ATP, small permission coin, not the self and not the goal, but the work it lets us join. Bridge: When the coin runs empty, many Gates grow still. A living cell must balance structure, need, and will. Ending: Mitochondria hum softly, not as kings but as flame. They keep the work permitted so the cell can keep its name.
