Electron Transport Chain in Respiration

How is oxygen used in cellular respiration?

• It accepts electrons and protons to form water.

• It is an electron carrier.

• It drives ATP synthesis.

• It reduces NADH + H+ and FADH2.

Which of the following happen during the Electron Transport Chain?

• Nothing happens

• H⁺'s diffuse through ATP Synthase, turning it so it can make ATP

• H⁺'s travel down the ETC, pumping high energy electrons into the intermembrane space

• High energy electrons travel down the ETC, pumping H⁺'s into the intermembrane space
