Heat and water deficit stresses tend to impede and restrict the efficiency of photosynthesis, chlorophyll fluorescence and maximum photochemical quantum yield in plants based on their characteristic ...

Photosystem II is the essential protein complex that drives the initial photochemical conversion of solar energy by catalysing the oxidation of water, an indispensable process in oxygenic ...

Under high-light conditions, photoprotective mechanisms minimize the damaging effects of excess light. A primary photoprotective mechanism is thermal dissipation of excess excitation energy within the ...

This is a preview. Log in through your library . Abstract With the aim to specifically study the molecular mechanisms behind photoinhibition of photosystem I, stacked spinach (Spinacia oleracea) ...

Using ultrafast, intensely bright pulses of X-rays scientists have obtained the first ever images at room temperature of photosystem II, a protein complex critical for photosynthesis and future ...

Helices are represented as cylinders. Chlorophylls of the D1/D2 reaction center are light green, pheophytins are blue. Chlorophylls of the antenna complexes are dark green, β-carotenes are in orange, ...

In the recent decade, scientists have paid more attention to studying light harvest for producing novel bionic materials or integrating naturally biological components into synthetic systems.

From providing living cells with energy, to nitrogen fixation, to the splitting of water molecules, the catalytic activities of metalloenzymes – proteins that contain a metal ion – are vital to life ...
