Which of the following statements concerning the complete oxidation of FADH2 in the electron transport chain is NOT true? a. In the final step, electrons from cytochrome c to O2 reducing it to H2O in complex IV, and four protons are transported from the intermembrane space to the matrix. b.In the first step, electrons from FADH2 are transferred in complex II to ubiquinone, which does not transport any proton across the inner mitochondrion membrane.c. In the second step, complex III transfers the electrons from ubiquinone to cytochrome c, and four protons are transported from the matrix to the intermembrane space. d. The complete oxidation of FADH2 causes transfer of 6 protons and yields two ATP.

Question

Which of the following statements concerning the complete oxidation of FADH₂ in the electron transport chain is NOT true?

In the final step, electrons from cytochrome c to O₂ reducing it to H₂O in complex IV, and four protons are transported from the intermembrane space to the matrix.

In the first step, electrons from FADH₂ are transferred in complex II to ubiquinone, which does not transport any proton across the inner mitochondrion membrane.

In the second step, complex III transfers the electrons from ubiquinone to cytochrome c, and four protons are transported from the matrix to the intermembrane space.

The complete oxidation of FADH2 causes transfer of 6 protons and yields two ATP.
