: How food is physically broken down (chewing) versus chemically transformed (enzymatic reactions). Typical Questions & Answers 1. What are the main functions of the digestive system? Mechanical processing : Grinding and mixing food.
: The role of the salivary glands, liver, and pancreas in secreting enzymes that break down food.
: Contains glands that secrete gastric juice and protective mucus. Submucosa : Contains blood vessels and nerves. biologiia dragomilov 8 klass stranitsa 100 otvety
: Three layers of smooth muscle that churn the food. Serosa : The outer protective covering. Study Tip: The "Enzyme-Substrate" Fit
: Understanding the sequence of organs: mouth, pharynx, esophagus, stomach, small intestine, and large intestine. : How food is physically broken down (chewing)
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.
To remember how enzymes work, think of a . A specific enzyme (the key) will only fit into a specific nutrient molecule (the lock) to break it down. Mechanical processing : Grinding and mixing food
