During Respiration,energy Flows in the Following Sequence

Question

During respiration,energy flows in the following sequence.
A)glucose → NADH → electron transport → oxygen
B)glucose → electron transport → NADH → proton-motive force → ATP
C)pyruvate → acetyl-CoA → electron transport → water
D)glucose → pyruvate → acetyl-CoA → CO₂
E)glucose → NADH → electron transport → proton-motive force → ATP

Accepted Answer

This sequence describes the process of oxidative phosphorylation, where energy from glucose is first used to produce NADH which then donates electrons to the electron transport chain. As the electrons are passed along the chain, protons are pumped across the inner mitochondrial membrane, creating a proton gradient which drives ATP synthesis through ATP synthase.
