Comments p.695 left column top paragraph:"2-Phosphoglycollate is salvaged via a complex pathway termed photorespiration, in which it is converted via glycolate to glyoxylate, transaminated to Gly, decarboxylated to Ser, and converted back via hydroxypyruvate and glycerate to 3PGA. This process results in a 25 to 30% decrease in the net rate of C fixation and a 20% decrease in quantum yield (primary sources)."
