The Kok cycle uses intermediate S states to explain the period-four damped oscillation in this reaction.
The Kok cycle uses intermediate S states to explain the period-four damped oscillation in this reaction.The color change of DCIP, from blue to colorless, is commonly used to demonstrate this reaction. Theprotein complex in which this reaction occurs has four manganese atoms and a calcium ion. It is driven bythe extremely strong oxidizing ability of P680+. This reaction, sometimes named for Robert Hill, occurs inthe absence of carbon dioxide. It results in the production of four electrons used to replace those lost byphotosystem II chlorophyll molecules. For 10 points, name this reaction which occurs in thelight-dependent reactions of photosynthesis in which water is split to produce a diatomic gas.
