During What Part of Aerobic Respiration Is the Majority of ATP Produced?


Quick Answer

The majority of adenosine triphosphate (ATP) molecules are produced during the electron transport chain. This is part of the final step in aerobic cell respiration and part of the oxidative phosphorylation process.

The four stages of aerobic respiration are glycolysis, the formation of acetyl coenzyme A, the citric acid cycle and the electron transport chain. The citric acid cycle is also known as the Krebs cycle. According to California Baptist University, the entire process creates a total of 36 ATP molecules. The electron transport chain produces 34 ATP molecules, while glycolysis and the citric acid cycle each synthesize two molecules of ATP. However, the initiation of glycolysis also consumes two molecules of ATP.
