Question

What happens when two hydrogen atoms enter the ETS as part of either NADH or FADH2? Two hydrogen and one oxygen react to form a molecule of water. The two hydrogen atoms are split into two H+ and two electrons. ATP is energized to form ADP in an anaerobic electron exchange. Oxygen is produced, while hydrogen is consumed to make ATP.

Answer 1

I think the correct answer from the choices listed above is the second option. When two hydrogen atoms enter the ETS as part of either NADH or FADH2, the two hydrogen atoms are split into two H+ and two electrons. Hope this answers the questions.

Answer 2

The correct answer is B- The two hydrogen atoms are split into two H+ and two electrons.

Hope this helped! :)
