NADH and FADH are oxidised and deliver hydrogen atoms.
A) FADH
B) NADH
C) hydrogen atoms
2. The hydrogens are split into electrons and H+ ions
A) H+ ions and electrons
3. The electrons are passed down carrier proteins in the membrane, the energy from the electron transport chain moves H+ ions into the intermembrane space against the concentration gradient
A) carrier protein
B) H+ ions
C) H+ ions
4. At the final carrier protein oxygen collects the 2 electrons along with 2 H+ ions to make water
A) final protein
B) oxygen
C) water
5. The H+ moves back into the matrix via ATP synthase to combine ADP and Pi to make ATP
