Energy transfer (ET) from protochlorophyllide to chlorophyll (Chl) was studied in the greening plants differing in the protochlorophyllide or Chl content and in a position of a short-wave Chl absorbtion band. It was shown that ET yield was not determined by the protochlorophyllide or Chl content. ET was observed in the leaves with the short-wave Chl absorbtion band at 670-671 mm. ET was not detected in the leaves with the short-wave Chl absorbtion band at 672 mm. These results suggest that the spatial arrangement of molecules of two pigments determines ET efficiency and the anergy acceptor is the fresh formed Chl in the short-wave form with the absorbtion band at 670-671 mm
