\nIt is accomplished in 3 different cell organelles viz chloroplast, peroxisome and mitochondria.
\n\n
(1) In chloroplast: In the presence of low concentration of CO2 and higher concentration of O2, high light intensity & higher temperature, RuBisCO functions as oxygenase. Therefore, it oxidises RUDP and one molecule of 3-PGA and one molecule 2-phosphoglycolate are formed. \n RUDP + O2 3-PGA + 2-phosphoglycolate.
\n\n
An inorganic phosphate separates from 2-phosphoglycolate to form glycolate which transfers into the peroxisome. \n 2-Phosphoglycolate Glycolate + H3PO4
\n\n
(2) In peroxisome: Glycolate reacts with oxygen to form glyoxylate which forms glycine through transamination.
\n\n
(3) In mitochondria: Glycine moves into mitochondria where in presence of oxygen, two molecules of glycine interact and give rise to a molecule of serine, CO2 and NH3.
\n\n
Serine moves back to peroxisome where deamination of serine takes place resulting in the formation of glycerate, which moves into chloroplast to form 3-PGA in the presence of ATP. 3-PGA is used in carbon assimilation cycle. \nAbout 30-40% of CO2 fixed during photosynthesis is lost during photorespiration.
