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
