Both photosystem (PS I and PS II) are affected by light with wavelengths shorter than 680nm (nanometer), while photosystem I is affected by light with wavelengths longer than 680nm. Photosystem I includes the following pigments: Chlorophyll b, Chlorophyll -a 670, Chlorophyll -a 680, Chlorophyll -a 695, Chlorophyll -a 700 or P700, Carotenoids.

Pigments Photosystem 1: PS 1 contains chlorophyll B, chlorophyll A-670, Chlorophyll A-680, chlorophyll A-695, chlorophyll A-700 and carotenoids. Figure emphasizes the structures of the three hetero-oligomeric complexes in the chain: (a) the hetero-dimeric photosystem II complex (Figure 3); molecular weight of cyanobacterial PSII complex≈350 kDa, containing 20 subunits, 35 chlorophyll molecules, 11 carotenoids, 14 lipids, 2 hemes, 1 non-heme iron, and the water-splitting Mn 4 CaO 5-cluster; (b) homo-trimeric photosystem I reaction Sammanfattning - Photosystem 1 vs Photosystem 2 De viktig skillnad mellan fotosystem 1 och fotosystem 2 är det fotosystemet 1 har ett reaktionscentrum som består av klorofyll en molekyl av P700 som absorberar ljus vid en våglängd på 700 nm. Å andra sidan har fotosystemet II ett reaktionscenter innefattande klorofyll, en molekyl av P680 som absorberar ljus vid en våglängd på 680 nm.

Caffarri, S., Passarini, F Das Photosystem I enthält insgesamt zirka 200 Moleküle Chlorophyll a und b sowie 50 Carotine.

Crystallographic investigations of cyanobacterial photosystem II have provided several medium-resolution structures (3.8 to 3.2 A) that explain the general arrangement of the protein matrix and cofactors, but do not give a full picture of the complex.
