Abstract

The apparent photosynthetic affinity of Anabaena variabilis for extracellular inorganic carbon (Ci) was strikingly increased by Na+. The effect was highly specific for Na+ and was maximal at 40 mM Na+. Na+ supply decreased the apparent K m (Ci) of the Ci transporting system and to a lesser extent increased V max. It did not affect photosynthetic rate expressed as a function of intracellular Ci. We infer an effect of Na+ on the Ci transporting system rather than on the photosynthetic machinery itself. We propose several possible models, including Na+‐H+ antiport for maintenance of intracellular pH during HCO3 uptake, and Na+‐HCO− 3 symport.
