  • question_answer
    In photorespiration cell organelles involved are

    A)  chloroplast, mitochondria and peroxisome

    B)  chloroplast, mitochondria and glyoxysome

    C)  chloroplast and mitochondria

    D)  chloroplast and golgi bodies.

    Correct Answer: A

    Solution :

    : Peroxisomes participate in photorespiration with   chloroplast   and   mitochondria. Photorespiration is light dependent uptake of\[C{{O}_{2}}\]. In contrast to normal respiration or dark respiration5 which occurs in the mitochondria, no ATP or reduced NAD is produced by photorespiration. The energy released being lost as heat. Photorespiration occurs in photosynthetic cell only whereas normal respiration occurs in all the living cells.
