Description

Photosynthetic fixation of 14C from solutions of NaH14CO3 (at constant concentrations of free CO2) by suspended leaf slices or isolated mesophyll cells from Chenopodium album is increased with increasing pH. Above all, the incorporation of radioactivity into amino acids and malate is stimulated. A direct uptake of HCO3 ions and its fixation by PEP carboxylase is suggested. Isolated mesophyll cells showed at pH 7.3 a higher rate of photosynthesis than at pH 5.0. (author)
