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 You Do? (City High song) from that included on the "Life" soundtrack as it features a sample of Dr. Dre's hit song, "The Next Episode". The song, along with the accompanying music video, is a motivational anthem for single parents dealing with poverty and especially acknowledging all the single mothers who feel forced into prostitution due to the need to support their children.
