6CO2 + 12 H2O ( C6H12O6 + 6O2 + 6 H2O. LIGHT AND DARK REACTIONS. When a molecule absorbs one photon of light, one of its electrons is energized and moves into a higher energy level (excited state). The excited electron may return to its original lower energy level (ground state) emitting a less energetic photon. This is called fluorescence. ................
