Where do the protons and electrons come from that are used in the electron transport chain quizlet?

All of the electrons that enter the transport chain come from NADH and FADH2 molecules produced during earlier stages of cellular respiration: glycolysis, pyruvate oxidation, and the citric acid cycle.

What molecule releases the electrons used in the electron transport chain?

-NADH and FADH2 deliver electrons to the electron transport chain during oxidative phosphorylation.
