Question
Give scientific reason : Bile is an important digestive juice though it does not contain any digestive enzymes.
✓
Answer
Bile is a greenish yellow alkaline digestive juice secreted from the liver cells.
Bile contains bile salts, certain bile pigments but does not contain any digestive enzymes.
The bile salts turn the acidic food from stomach, alkaline and thereby provide alkaline medium for further reactions in intestine.
Pancreatic enzymes and intestinal enzymes need alkaline medium.
Bile salts emulsify the large fat globules into a very large number of very minute fat droplets and thereby greatly increase the exposed surface area of fat for the rapid action of lipases.
Hence bile is an important digestive juice though it does not contain any digestive enzymes.
