    The first reaction in photorespiration is :

    A)  Carboxylation                  

    B)  Decarboxylation

    C)  Oxygenation                    

    D)  Phosphorylation

    Correct Answer: C

    Solution :

                     Photorespiration is also called light respiration It is a process in which rate respiration increases under the influence of light. In this process, \[C{{O}_{2}}\]is released and \[{{O}_{2}}\]is used but ATP are not formed. The first step of photorespiration is oxygenation This process is also called oxidame  photosynthetic carbon cycle because the oxidation of respiratory substrate take place in this process.
