The document defines and explains the stages of aerobic respiration including glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis breaks down glucose to produce pyruvate and ATP. The Krebs cycle further breaks down pyruvate to produce NADH, FADH2, ATP, and carbon dioxide. The electron transport chain uses NADH and FADH2 to produce ATP through oxidative phosphorylation. In total, the complete aerobic respiration of one glucose molecule produces approximately 30-32 molecules of ATP.
