WebPhotosynthesis begins with photo-absorption by pigments located in the thylakoid membranes. The only pigment present in all oxygen producing phytoplankton is chlorophyll-a and it is the essential pigment required for photosynthesis. Most light absorption, … WebWhen an analyte absorbs an ultraviolet or visible photon, one of its valence electrons moves from the ground state to an excited state with a conservation of the electron’s spin (Figure 10.47b). Emission of a photon from the singlet excited state to the singlet ground state—or between any two energy levels with the same spin—is called fluorescence.
