the biosynthetic pathway of carotenoid synthesis involves several steps of desaturation requiring free energy, for instance the transition from phytoene to phytofluene achieved by phytoene desaturase. This reaction is associated with a reduction of plastoquinone. The oxidation of the plastoquinol is then achieved by a plastoquinol:oxygen oxidoreductase. Might additionally mediate the reduction of plastoquinone by internal reductants
