Inside an active mitochondrion, most electrons follow which pathway?
A) NADH → oxidative phosphorylation → ATP → oxygen
B) citric acid cycle → FADH₂ → electron transport chain → ATP
C) electron transport chain → citric acid cycle → ATP → oxygen
D) citric acid cycle → ATP → NADH → oxygen
E) citric acid cycle → NADH → electron transport chain → oxygen

Question

Quizplus · Accepted Answer

Electrons from NADH produced in the citric acid cycle are transferred to the electron transport chain, where they ultimately reduce oxygen to form water.
