The complex responsible for this reaction lies on the lumen side of the thylakoid membrane, and it's driven by the oxidizing power of P680 For 10 points, name this reaction which immediately precedes the entry of electrons into photosystem II, in which water is oxidized.
The PsbP protein and PsbQ protein are required for this process. This reaction turns the dye DCIP colorless. The mechanism of this process was elucidated using periodic discharges of a Joliot electrode by Bessel Kok, who proposed that the complex responsible for catalyzing it oscillated between five different S-states. Sometimes named for Robert Hill, this reaction is catalyzed by a complex that contains a single calcium and four manganese atoms in a (*) cluster. Four products of this process are later used to reduce two molecules of plastoquinone.
