A) chloroptast to proxysome
B) succinyl Co-A to succinic acid
C) succinic acid to fumaric acid
D) fumaric acid to malic acid
Correct Answer: B
Solution :
Photorespiration or photosynthetic carbon oxidation, universal in \[{{C}_{3}}\]-plant, involves three cell organelles; chioroplast, peroxysomes and mitochondria. During cycle RUBP is oxidized into phosphoglyceric (molecule) and phosphogiycolic acids. Enzyme phosphotase hydroiyse phosphogjycolic acid into glycolic acid. Chloroplast membrane contain transporter protein for glycolic acid and glycolic acid enters from chioroplast to peroxysomes. Now it strats photosynthetic carbon oxidation. Glycolic acid is oxidised to glyoxylic acid and \[{{H}_{2}}{{O}_{2}}\] and glyoxylic acid is aminated to form amino acid glycine with the help of transaminase. Giyoxylic acid + Glutamic acid \[\xrightarrow{transaminase}\]
