The operation of the photorespiratory (C2) pathway involves cooperative interaction among three separate subcellular organelles, namely, chloroplast, mitochondria and peroxisomes. Following are certain statements regarding C2 pathway: A. 2-phosphoglycolate formed in the chloroplast is converted to glycolate by the action of phosphoglycolate phosphatase. B. Glycolate exits chloroplast by diffusion and enters peroxisome through a glycolate transporter. C. In the peroxisomes, glycolate reacts with O2 and produces glyoxylate and H2O2. D. Only serine:glyoxylate aminotransferase is involved in the conversion of glyoxylate into serine in a peroxisomal reaction.
