Place the following steps of the electron transport system (ETS)and ATP formation in the correct order. 1.Movement of hydrogen ions provides energy to ATP synthesis.
2)Electrons from FADH₂ pass to coenzyme Q.
3)Electrons are transported to respiratory complex III.
4)ADP combines with P to form ATP.
5)Electrons from NADH pass to coenzyme Q.
6)Electrons combine with oxygen and hydrogen ions to form water molecules.

Question

Quizplus · Accepted Answer

The correct order of steps in the ETS and ATP formation is as follows:
1. Electrons from NADH pass to coenzyme Q.
2. Electrons from FADH₂ pass to coenzyme Q.
3. Electrons are transported to respiratory complex III.
4. Electrons combine with oxygen and hydrogen ions to form water molecules.
5. Movement of hydrogen ions provides energy to ATP synthesis.
6. ADP combines with P to form ATP.
This sequence of events occurs during oxidative phosphorylation in the mitochondria to produce ATP through the ETS. Therefore, choice B is the correct answer.
