Chapter 7: How cells make ATP: Energy-Releasing Pathways Write a summary reaction for aerobic respiration, showing which reactant becomes  oxidized and which becomes reduced: Aerobic respiration  is a catabolic process in which a fuel molecule such as glucose is broken  down to form carbon dioxide and water. It includes  redox reactions  that result in the transfer of  electrons from glucose (which becomes  oxidized ) to oxygen (which becomes  reduced ) C6 H12 O6 + 6 O2       6 CO2 + 6 H2O + energy Energy released during aerobic respiration is used to produce up to 36 to 38 ATPs per molecule  of glucose. List and give a brief overview of the four stages of aerobic respiration: The chemical reactions of aerobic respiration occur in four stages: glycolysis, formation of acetyl  CoA, the citric acid cycle, and the electron transport chain/chemiosmosis. During  glycolysis , a molecule of glucose is degraded to two molecules of  pyruvate . Two ATP  molecules (net) are produced by  substrate-level phosphorylation  during glycolysis. Four  hydrogen atoms are removed and used to produce two NADH. During the formation of  acetyl CoA , the two pyruvate molecules each lose a molecule of carbon  dioxide, and the remaining acetyl groups each combine with  coenzyme A
