The relationship between rate of photosynthesis and CO2 concentration has been reinvestigated using isolated spinach (Spinacia oleracea) chloroplasts. The apparently low CO2 concentration required for half-maximal photosynthesis is shown to result partly from a ceiling imposed by electron transport....
