Human cells can metabolize lipids, alcohol, and proteins for energy. Lipids are broken down into fatty acids and glycerol, which can be used in cellular respiration. Alcohol is metabolized by the liver into acetaldehyde and then into acetyl-CoA, which can enter the citric acid cycle. Proteins are broken down into amino acids, which can be used in gluconeogenesis or directly in the citric acid cycle. Water, however, is not a source of energy but is essential for various metabolic processes.
