The redox potential of water is +820 mV which means this molecule has a very high affinity for electrons. To oxidize water requires altering this potential or pairing this molecule with another molecule that has an even greater redox potential. Photosystem II and the water-splitting enzyme oxidize water by which mechanism? A. The water-splitting enzyme uses energy from ATP to excited water to a lower redox state (-620 mV) B. The special pair of chlorophyll in photosystem II is excited to a very high redox potential by light (+1200 mV) C. The special pair of chlorophyll in photosystem II have a very high redox potential in their unexcited state (+1200 mV) D. Photosystem II uses light energy to excited water to a lower redox state (-620 mV)
