Electron Transport Chain.
Explanation: oxidative phosphorylation (ETC + ATP synthase) produces the bulk of ATP — roughly 26–28 ATP per glucose. The Krebs (Citric Acid) cycle directly makes only 2 ATP (as GTP) per glucose (but also yields NADH/FADH2 that feed the ETC). Fermentation yields no additional ATP beyond the 2 from glycolysis.
