It's important to know how many ATP, or adenosine triphosphate, are produced per glucose molecule by various metabolic pathways, such as the Krebs cycle, fermentation, glycolysis, electron transport, and chemiosmosis. Take a look at how many net ATP are produced per pathway and which yields the most ATP per glucose.

Here is the breakdown of net ATP production:

So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.
