Claim 1component compositionsupports2003Source 1DOI PubMed

The photosystem II core contains the inner light-harvesting complexes CP43 and CP47, which harbor 13 and 16 chlorophyll pigments respectively.

Claim 2environmental dependencesupports2003Source 1DOI PubMed

The composition and organization of the photosystem II light-harvesting system are modular and depend on environmental conditions, especially light quality and intensity.

Claim 3functional architecturesupports2003Source 1DOI PubMed

The photosystem II reaction center can handle more photons than are absorbed by its own pigments, so additional excitations are provided by surrounding light-harvesting complexes.

Claim 4mechanistic rolesupports2003Source 1DOI PubMed

The photosystem II reaction center is the site of sunlight-induced charge separation.

Claim 5mechanistic rolesupports2003Source 1DOI PubMed

Water oxidation in photosynthesis takes place in photosystem II.

Claim 6structural organizationsupports2003Source 1DOI PubMed

Outer light-harvesting complexes surround the photosystem II core and together form supercomplexes in plants.
