Photosynthesis called P680. The source of electrons for photosynthesis in green plants and cyanobacteria is water. Two water molecules are oxidized by four successive charge-separation reactions by photosystem II to yield a molecule of diatomic oxygen and four hydrogen ions. The electrons yielded are transferred to a redox-active tyrosine residue that then reduces the oxidized P680. This resets the ability of P680 to absorb another photon and release another photo-dissociated electron. The oxidation of water is catalyzed in photosystem II by a redox-active structure that contains four manganese ions and a calcium ion; this oxygen-evolving complex binds two water molecules and
What would Jesus do? expression has become a snowclone, sometimes for humorous effect. For example, "What Would Jesus Buy?", "What Would Lincoln Do?", "What Would Brian Boitano Do?", "What Would Mary Marvel Do?", "What Would Johnny Cash Do?", and "What would Tintin do?". The term "What Would Jesus Do?" or "WWJD" is also perceived as a fundamental management and leadership principle given Jesus' methodology of going to the marketplace to preach and lead by example. In modern management principles, more academic and professional references are going to the gemba or Management by Walking Around. What would Jesus do? The phrase "What would Jesus do?"
