The complete oxidation of one glucose molecule yields 30 or more ATP . Glucose catabolism includes glycolysis, pyruvate oxidation, and the citric acid cycle. The total yield of ATP includes ATP , GTP , and reduced cofactors that yield ATP from the electron transport chain and oxidative phosphorylation. Which processes yield the most ATP

Electron transport chain.

Explanation:

Electron transport chain is the process which yield the most number of ATP as compared to all three major phases of cellular respiration. Glycolysis produces only 2 ATP from the breakdown of molecule of glucose. In the Krebs cycle, one GTP which is an ATP equivalent is produced from the breakdown of one glucose molecule while on the other hand, 32 ATP molecules are produced from the breakdown of one glucose molecule.
