Question

What stage of cellular respiration uses the high-energy electrons from NADH and FADH2 to form ATP molecules?

Krebs cycle

Electron transport chain

Fermentation

Glycolysis

Answer 1

Electron transport chain

AD+ and NADH: NAD+ is an electron carrier that accepts a pair of high-energy electrons to become NADH. The NADH carries the high-energy electrons to the electron transport chain where they are used to build high-powered ATP molecules.

Answer 2

I think the correct answer among the choices listed is the first option. Krebs Cycle is the stage of cellular respiration uses the high-energy electrons from NADH and FADH2 to form ATP molecules. It is th central metabolic pathway of ll aerobic organisms.
