Experiments with Chlorella show that glycine and serine both become radioactive during photosynthetic incorporation of radioactive carbon dioxide. By contrast, when radioactive glucose is fed to Chlorella in the dark, alanine, glutamate, and aspartate are the major products. These are not produced in significant amount during photosynthesis at low concentrations of carbon dioxide but their formation may be stimulated by the addition of ammonium ions.
