Active transport of inorganic carbon into cells of blue-green algae (Cyanophyta)
RÉSUMÉ
The review is devoted to studies in energy requirements of the mechanisms supplying the active transport of inorganic carbon (Ci ) into cells of blue-green algae. The data presented show that either the energy of the transmembrane eleetrochemical potential of hydrogen ions (DmH+) ог the transmembrane eleetrochemical potential of sodium ions (DmNa+) supplies the active transport of Ci via the plasmalemma of the Cyanophyta cells only within very narrow limits of environmental conditions. Neither (DmH+) nor (DmNa+(DmNa+) may be considered a universal source of energy for Ci transport. An assumption is advanced that the energy for the active transport of Ci is provided at the expense of ATP hydrolysis by НСО3- transport ATPase, the electron-transport chain of photosystem I participating directly.
