Figure 4.8. 1: Photosystems. Light is absorbed by the antenna pigments of photosystems II and I. The absorbed energy is transferred to the reaction center chlorophylls, P 680 in photosystem II, P 700 in photosystem I. Absorption of 1 photon of light by Photosystem II removes 1 electron from P 680. WebIn the case of photosynthesis and chlorophyll (Chl) fluorescence, the absorbed energy is solar energy in a spectral region almost identical with visible light, i.e. in the interval 400 -700 nm for most of photosynthetizing systems. ...
