Final answer:
Metabolic water is formed when organisms break down food in cellular respiration. Water is involved in many biochemical reactions and is essential for life processes.
Step-by-step explanation:
Metabolic water is formed when organisms break down food in cellular respiration. In this process, cells break down glucose in the presence of oxygen and release carbon dioxide, water, and energy. The reactions of cellular respiration involve the chemical equation C6H12O6 + 602 → 6CO₂ + 6H₂O + Energy. Water is involved in many biochemical reactions and is essential for life processes.
