Digestion changes food into substances which the body can use. This is a series of chemical changes where the food molecules react with water in the presence of enzymes to produce smaller, soluble molecules.
- saliva in the mouth contains enzymes that break some starches down to glucose
- hydrochloric acid and enzymes in the stomach denature proteins and break them down to amino acids
- enzymes in the small intestine break fats down to fatty acids
- enzymes in the small intestine break starches down to glucose
- bacteria in the large intestine break complex carbohydrates down to glucose

Oxidizing food for energy-physical change?
When food is oxidized for energy in the body, it undergoes a chemical change rather than a physical change. Oxidation involves the breaking down of molecules to release energy, which is a fundamental process in our metabolism. This process transforms the chemical energy stored in food molecules into a form that the body can use for various biological functions.
