Photosystem

The missing parts, known as photosystem II, carry out the stage in photosynthesis that generates oxygen by splitting water molecules. ❋ Unknown (2010)

There are membrane proteins implanted into the surface of the thylakoid called photosystem II and photosystem I that have a pigment called chlorophyll located on the top of these proteins. ❋ Unknown (2010)

These proteins, known as photosystem I, contain arrays of some 200 light-gathering chlorophyll molecules that use photons to free up electrons for fixing carbon dioxide into sugars. ❋ Unknown (2010)

Their work focuses on one of two photosynthesis complexes, known as photosystem I (PSI; the other is photosystem II, PSII). ❋ Unknown (2010)

"Plants do this with a complex molecular 'photosystem' that uses the energy of sunlight to break apart water molecules, liberating electrons, hydrogen ions and oxygen," according to the Economist. ❋ Unknown (2010)

Separate photosensitizers mediate degradation in the 32-kda photosystem II reaction center protein in the visible and UV spectral region. ❋ Unknown (2009)

Now a different team has found new evidence that points to a closely packed pigment-protein complex of the photosystem as the key to those quantum mechanical effects. ❋ Unknown (2007)

Quantum-mechanical effects enable a plant's photosystem to simultaneously sample all the potential energy pathways from pigment molecules to reaction centers and choose the most efficient one. link ❋ Unknown (2007)
