Figure 5. The active ATP Synthase complex. The movement of hydrogen ions (red arrow) results in the rotation of the "c" (yellow) complex as indicated by the brown arrow. The attached g protein (green rod) is also rotated. The surrounding hexamer (red and blue) is held stationary by interaction between the "b" protein (purple) of the F0 complex and the d protein (brown) of the F1 complex.
