The copper atom bound to the plastocyanin is in the shape Cu<sup>2+</sup>. | The copper atom bound to the plastocyanin is in the shape Cu<sup>2+</sup>. This this shape of plastocyanin is reduced by the cytochrome b<sub>6</sub>f according to the following reaction : | ||
Cu<sup>2+</sup>Pc + e<sup>-</sup> → Cu<sup>+</sup>Pc | |||
The electron is given up by the cytochrome b<sub>6</sub>f and transforms plastocyanin in shape Cu<sup>2+</sup> into plastocyanin in shape Cu<sup>+</sup>. | |||
Then this plastocyanin diffuses through the lumen of thylakoid (remember its localisation in intern membrane of the thylakoid) until the recognition and binding occurs with the photosystem I. | |||
