Cellular respiration converts glucose to ATP: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 36-38 ATP. Three stages: 1) Glycolysis (cytoplasm): glucose → 2 pyruvate + 2 ATP + 2 NADH. 2) Krebs Cycle (mitochondrial matrix): pyruvate → CO₂ + 2 ATP + 8 NADH + 2 FADH₂. 3) Electron Transport Chain (inner mitochondrial membrane): NADH/FADH₂ → 34 ATP via oxidative phosphorylation. Without O₂, only glycolysis occurs (fermentation: produces lactic acid or ethanol).
