3.5 Notes

digestion: the process of breaking down the complex molecules of food into smaller molecules
mechanical digestion: a physical process in which large pieces of food are torn and ground into smaller pieces
chemical digestion: the process of breaking down larger molecules into smaller ones


Why must your body digest food?
Foods must be broken down into simpler substances that your body can use for raw materials and energy.
How does pH affect digestion?
Some digestive enzymes work at a low pH. For others, the pH must be high or neutral.
