Does the digestive system dissolve food for energy?

No, the digestive system does not dissolve food for energy. The digestive system breaks down complex food molecules into simpler molecules that can be absorbed and used by the body for energy. The process of digestion involves various mechanical and chemical processes, including chewing, churning, and mixing, as well as the secretion of digestive enzymes. These enzymes break down carbohydrates, proteins, and fats into smaller molecules such as glucose, amino acids, and fatty acids, which can then be absorbed into the bloodstream and used by the body's cells for energy production.
