    I have no clue and need help on this one.

    A second metabolic process involves the net production of 2 ATP and 2 NADH from 2 ADP and 2 NAD+. If the conversion of these molecules is endothermic and adds 443.5 kJ to the overall enthalpy of the rxn, find the enthalpy for a "high-energy" phosphate bond.

    Ans = 338.5 kJ/mol

    Given but I am not sure it's necessary.

    O=O 497
    C=O 805
    O-H 464
    C-C 347

    Thanks!!!
