Quizplus · Accepted Answer

Statement 1 is false because FADH2 is the reduced form of FAD. Statement 2 is false because not all electron carriers in the ETC contain iron; only some do, and cytochrome c oxidase contains copper. Statement 3 is false because one turn of the CAC generates two CO2 molecules, three NADH molecules, and one FADH2 molecule.
