    The number of ATP molecules produced by electron transport system from Krebs cycle intermediates in a single turn is :

    A)  11              

    B)  14

    C)  12              

    D)  16

    Correct Answer: A

    Solution :

    Total energy production is \[\text{3NADH+ }{{\text{H}}^{\text{+}}}\text{1FAD}{{\text{H}}_{\text{2}}}\]and\[\text{1 ATP/GTP}\]. Intermediates form ATP on ETS. It is\[3\times 3\](For \[\text{NADH+}{{\text{H}}^{\text{+}}}\])\[2\times 1\](for\[\text{FAD}{{\text{H}}_{\text{2}}}\]) or 11.
