from thylakoids Gasanov et al 1979 calculated the efficiency of excitation energy transfer from the carotenoids without distinction between carotenes and xanthophylls to Chl a Figure 7 It appears that there are two pools of carotenoids one absorbing at shorter wavelengths and transferring energy to Chl a with an efficiency of about 40 50 and another at
