82. The researchers used genetic manipulation to enable the experimental mice to metabolize glucose and fatty acids, but not acetic acid, and then compared these experimental mice with normal experimental mice when they were fed with food and fasted for 48 hours. It was found that the body temperature and endurance of experimental mice that could not metabolize acetic acid were significantly reduced under the condition of being forced to fast for a long time. Acetic acid is the basic substance in life, and the body structure of experimental mice is very close to the human body. Introduced from this? ["Acetic acid plays a vital role in maintaining the body's energy supply.", 'Acetic acid can be used as an energy source that does not raise blood sugar.', 'etabolism adenosine triphosphate is the energy source of life activities.', 'Fatty acids and ketone bodies are the main sources of ATP during prolonged exercise.']
