: Three layers of smooth muscle that churn the food. Serosa : The outer protective covering. Study Tip: The "Enzyme-Substrate" Fit Mechanical processing : Grinding and mixing food
: Contains glands that secrete gastric juice and protective mucus. Submucosa : Contains blood vessels and nerves.
Enzymes are biological catalysts. On page 100, the text usually emphasizes that enzymes are specific (each enzyme only breaks down a certain type of nutrient) and require specific conditions, such as a particular temperature ( ) and acidity level (pH), to function correctly.
