WebThe reaction centre of photosystem II is called P 680, whereas reaction centre of photosystem I is called P 700. In photosystem II the electrons emitted by reaction centre are first captured by pheophytin whereas in photosystem I, the electrons emitted by reaction centre are first captured by iron sulphur protein. WebApr 1, 1991 · It is believed that the initial chemical reaction in photosynthesis is the successive emission of electrons from a reaction centre - photosystem 2, PS2 - followed by the oxidation of water. surfactant concentration was observed. Among those surfactants tested, Na-cholate exhibited the least apparent acceleration, while the C-16 CTAB had the ...
