In the sunlight reaction, in photosynthesis, plastocyanin is an important electron donor to the Photosystem I (P700).Thanks to its hydrophobic surface, plastocyanin is localised in the intern membrane of the thylakoid in chloroplasts. Its redox potential, about 370 mV, has allowed to determine the place of plastocyanin in the electron transport chain (between the photosystem II and the photosystem I): between the cytochrome b<sub>6</sub>f complex and the photosystem I. | In the sunlight reaction, in photosynthesis, plastocyanin is an important electron donor to the Photosystem I (P700).Thanks to its hydrophobic surface, plastocyanin is localised in the intern membrane of the thylakoid in chloroplasts.
