Which of the following statements is False?

#Section 2: General Biology
  1. In chloroplast stroma, glycolate is oxidized by molecular oxygen, and the resulting aldehyde (glyoxylate) undergoes transamination to glycine
  2. The photorespiration, is a costly side reaction of photosynthesis, a result of the lack of specificity of the enzyme rubisco
  3. glycine decarboxylase complex oxidizes glycine to CO2+ and NH4+, with the concomitant reduction of NAD+ to NADH is takes place in Mitochondria
  4. The active site on Rubisco for carboxylation and oxygenation is different
