What stage of cellular respiration yields the most ATO?

The stage of cellular respiration that yields the most ATP is oxidative phosphorylation, which occurs during the electron transport chain and chemiOSmosis. This process generates approximately 26 to 28 ATP molecules per glucose molecule by utilizing the proton gradient created by the movement of electrons through the electron transport chain. In total, cellular respiration can produce up to about 30 to 32 ATP molecules per glucose, with oxidative phosphorylation contributing the largest share.
