The fate of RuBP in Photorespiration is to form
|
|
phosphoglycolate and PGA
|
|
|
two PGA molecules
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Photorespiration involves the oxygenation of ribulose-1, 5-bisphosphate (RuBP) to form 3-phosphoglycerate (3PGA) and 2-phosphoglycolate (2PG) and the subsequent carbon oxidation pathways that release CO2 under light conditions [1, 2, 3, 4, 5].
Detailed explanation-2: -It happens due to oxygenase activity of RuBisCO. Due to oxygenase activity of RuBisCO, oxygen rather than carbon dioxide is fixed in the first reaction of Calvin cycle. Here the RuBP instead of being converted to 2 molecules of phosphoglyceric acid (PGA) binds with O2 to form one molecule of PGA and phosphoglycolate.
Detailed explanation-3: -Totally 3 molecules of phosphoglyceric acids are formed at the end of photorespiration.
