Comments | "The efficiency of transfer of excitation energy from the chromophore that absorbed the photon to the reaction centre is very high (Collins et al. 2010 Hossein-Nejad et al. 2011 Hildner et al. 2011). The photon yield of primary photochemistry is one electron per absorbed photon in PSI and <0.8 electrons per absorbed photon in PSII (Falkowski and Raven 2007 Johnsen and Sakshaug 2007 Hogewoning et al. 2012) therefore, the reduction of two NADP+ and production of one O2 need at least 4+(4/0.8) = 9 photons (Table 1)." |
