Under standard conditions, is the oxidation of NADH by free FAD sufficiently exergonic to drive the synthesis of ATP?
A) no, as oxidation of NADH by FAD only generates -9.65 kJ/mol
B) no, as oxidation of NADH by FAD only generates -19.3 kJ/mol
C) no, as oxidation of NADH by FAD only generates 9.65 kJ/mol
D) no, as oxidation of NADH by FAD only generates 19.3 kJ/mol
E) yes, as oxidation of NADH by FAD generates -104.2 kJ/mol

The oxidation of NADH by free FAD only generates -19.3 kJ/mol, which is not sufficient to drive the synthesis of ATP under standard conditions. This is because the overall reaction for ATP synthesis from ADP and Pi has a standard free energy change of about -30.5 kJ/mol.
