Metabolic water, which keeps some desert animals such as the kangaroo rat alive without drinking, is produced inside cells mainly during
- A. the hydrolysis of glycogen
- B. the conversion of pyruvate to lactate
- C. alcoholic fermentation
- D. the aerobic oxidation of glucose
Explanation
At the end of the electron transport chain, oxygen accepts electrons and hydrogen ions and is reduced to water, so aerobic respiration generates metabolic water. Fermentation pathways do not produce water, and hydrolysis consumes water rather than releasing it.
