    Oxidative phosphorylation is the formation of                                                                   

    A)  \[NADP{{H}_{2}}\] in respiration

    B)  ATP in respiration

    C)  \[NADP{{H}_{2}}\] in photosynthesis

    D)  ATP in photosynthesis

    Correct Answer: B

    Solution :

    With the release of 2 electrons and 2 hydrogen atoms from every molecule of NAD-2H and their reaction with oxygen, 3 ATP molecules are synthesized. For the synthesis of each molecule of ATP, 7.3 kcal of energy is stored. This process is called photophosphorylation. Because this occurs in respiration in the presence of oxygen it is called oxidative phosphorylation.
