The C2 oxidative photosynthetic carbon cycle on chloroplast metabolism, the functioning of the C2 oxidative photosynthetic cycle in three compartments: chloroplasts, peroxisomes and mitochondria such as;
a.) In the carbon cycle; the transfer two molecules of glycolate and recovers one molecule of glycerate and releases one molecule of CO2
b.) In the nitrogen cycle, one molecule of glutamate and recover one molecule of NH4 +
c.) In the oxygen cycle; contributes to the removal of H2O2 formed in the oxidation of glycolate by O2
i) Takes place in Peroxisome
ii) In Mitochondria
iii) In the Chloroplasts
