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 You Need (song) What You Need (song) "What You Need" is a song recorded by the Australian band INXS. It is the leadoff track from their 1985 album, "Listen Like Thieves". "What You Need" was the first single off the album in Australia and New Zealand, while it was in USA and Europe the second single after "This Time" and was the band's first American Top Ten hit, peaking at #5 on the "Billboard" Hot 100 singles chart. After the album "Listen Like Thieves" was recorded and ready to be given to the record label for inspection, producer Chris Thomas was worried that
