Digestive juices and enzymes
Digestive juices are fluids that contain enzymes and other substances that break complex food into simpler forms.
Practice This ConceptMain explanation
Teacher explanation
Saliva, gastric juice, bile, pancreatic juice, and intestinal juice each act on specific food components. Enzymes speed up digestion without being used up. Bile helps by making the medium alkaline and by emulsifying fats, so the enzymes can work better.
Example
Salivary amylase starts starch digestion in the mouth, and pancreatic enzymes act in the small intestine.
Simple analogy
Juices assist, enzymes cut, bile prepares.
Common confusion
Students think bile is an enzyme or that all enzymes act on all food.
Exam tip
Remember which juice acts where and on which food group.
