Vedclass · Answer

(D) Photorespiration is a complex metabolic pathway that involves the cooperation of three different cell organelles: the $Chloroplast$, the $Peroxisome$, and the $Mitochondria$.$1$. In the $Chloroplast$, the enzyme $RuBisCO$ acts as an oxygenase, reacting $RuBP$ with $O_2$ to form $2$-phosphoglycolate.$2$. The $2$-phosphoglycolate is then transported to the $Peroxisome$, where it is converted into glycine.$3$. Glycine is then transported to the $Mitochondria$, where it is converted into serine, releasing $CO_2$ and $NH_3$.$4$. Finally, the serine returns to the $Peroxisome$ and then to the $Chloroplast$ to regenerate $RuBP$.Since all three organelles are essential for the completion of this pathway, the correct answer is $All\,of\,the\,above$.

Which of the following organelles is responsible for photorespiration?
