The Electron Transport Chain.

It produces the majority of ATP by using electrons from NADH/FADH2 to pump protons across the inner mitochondrial membrane, creating a proton gradient that drives ATP synthase (oxidative phosphorylation). Glycolysis and the Krebs cycle yield only small amounts (about 2 ATP each total), and fermentation does not produce additional ATP beyond glycolysis.
