The chlorophyll a-specific light absorption cross-section ranged from 3 to 6×10-3 m2 mg-1 chl a and was lowest at low PFDs due to intracellular self-shading of pigments associated with high cell-chlorophyll a contents. The C:chl a ratio increased from 10 to 40 mg C mg-1 chl a ...
To investigate the light response of the combined pigments and LPMO-catalysed cellulose oxidation, experiments were performed using blue, red, green and sunlight with the same range of intensity. In accordance with the absorption spectra of chlorophyll pigments: sunlight, blue and red light induced ...
A proxy of package effect was estimated from the phytoplankton absorption spectra, independently of chlorophyll a. Variations in the concentration of photosynthetic and photoprotective pigments were discernible by changes in this metric but not in the chlorophyll a specific absorption coefficient of ...
Analysed by differential spectroscopy, 1208 empirical spectra of light absorption iasubpl/sub/i(#x03BB;) by Baltic phytoplankton were spectrally decomposed into 26 elementary Gaussian component bands. At the same time the composition and concentrations of each of the 5 main groups of pigments (chlo...
By optical (UV–visible) and X-ray absorption spectroscopy, we show that the light-driven oxidation of Mn2+ ions results in Mn-oxide nanoparticles which are bound to the photosystem, thereby supporting that also ancient photosystems could have produced Mn oxides and suggesting a viable ...
Pigments produced from porphyrins that can function as chromophores for photoreceptors and photosynthetic light-harvesting proteins. Photocycle The series of structural changes that a photoreceptor undergoes upon light absorption before returning to its initial structure. Optogenetics The biological engineering ...

light reactions of the photosynthetic process. It is now possible also to isolate the entire chloroplast so that it can carry out the complete process of photosynthesis, from light absorption, oxygen formation, and thereductionof carbon dioxide to the formation of glucose and other products....
