State
The citric acid cycle carries a two-carbon acetyl group through eight steps of oxidation, releasing two carbon dioxide molecules and harvesting electrons and one ATP-equivalent molecule per turn.
Watch for
The citric acid cycle produces very little ATP directly — its real yield is the electron carriers NADH and FADH2, spent in the pathway that follows.
