Slow exciton trapping in Photosystem II: A possible physiological role.

Photosynthesis research

Jennings RC, Garlaschi FM, Finzi L, Zucchelli G.
PMID: 24301824
Photosynth Res. 1996 Feb;47(2):167-73. doi: 10.1007/BF00016179.

Photosystem II, which has a primary photochemical charge separation time of about 300 ps, is the slowest trapping of all photosystems. On the basis of an analysis of data from the literature this is shown to be due to...

Selective quenching of the fluorescence of core chlorophyll-protein complexes by photochemistry indicates that Photosystem II is partly diffusion limited.

The spectral characteristics of fluorescence quenching by open reaction centres in isolated Photosystem II membranes were determined with very high resolution and analysed. Quenching due to photochemistry is maximal near 687 nm, minimal in the chlorophyll b emission interval...

PMID: 24424434
Photosynth Res. 1989 Jun;20(3):207-20. doi: 10.1007/BF00034065.

An experimental analysis is presented concerning the effect on relative light absorption by the two photosystems caused by (a) a highly light scattering environment (the "detour effect") and (b) light filtration across successive chloroplast layers (the "light attenuation effect")....
