Some desert organisms can live out their life without ever drinking liquid water. What phase (s) of cellular respiration could provide the organism with water?

Glycolysis

Electron transport chain (ETC)

Explanation:

Glycolysis breaks down the one molecule of glucose into two molecules of pyruvate through a series of reactions. Dehydration of 2-Phosphoglycerate into phosphoenolpyruvate releases two molecules of water for one glucose molecule. The reaction is catalyzed by enolase. During the electron transport chain, reducing powers NADH and FADH2 give their electrons to the molecular oxygen via a series of proteins. The process reduces the molecular oxygen into the water. Therefore, glycolysis and ETC are the sources of water for desert animals.
