Bile juice contains no digestive enzymes , yet it is important for digestion. Why ?

Explanation

1. Bile is produced by the Liver. The Bile duct from the liver joins the pancreatic duct and pours its secretions into duodenum.
2. The bile contains bile pigments (bilirubin and biliverdin ) as the break down products of haemoglobin of dead RBCs, bile salts, cholesterol and phospholipids but has no enzymes .
3. Bile helps in emulsification of fats . Bile salts reduce the surface tension of fat droplets and break them into small globules. Bile also activates lipases to digest lipids.
4. Thus the bile is very important for digestion through it does not contain any enzymes .
