Photo respiration involves oxidation of
Answers
Answer:
Photorespiration is the oxygenation of RuBP by RUBISCO followed by photorespiratory glycolate metabolism. Competition between O2 and CO2 reduces the rate of carbon assimilation, energetic efficiency of photosynthesis, and may reduce the photosynthetic quotient (PQ = O2 evolved/CO2 assimilated).
Explanation:
Answer:
Photorespiration occurs due to fact that the active site of enzyme Rubisco (ribulose bisphosphate carboxylase oxygenase) is same for both carboxylation and oxygenation. The oxygenation of RuBP (ribulose bisphosphate) in the presence of O2 is first reaction of photorespiration that leads to the formation of one molecule of phosphoglycolate, a two-carbon compound and one molecule of PGA.
