Correct Answer - Option 4 : All the above functions

The correct answer is All the above functions.

• Bile juice is a digestive juice secreted by the liver.
• Bile juice consists of bilirubin and biliverdin, bile salts, and cholesterol.
• Bile juice helps in the emulsification of fat.
  • Bile juice breaks down large fat globules into smaller globules so that the pancreatic enzymes can easily act on them.
• Bile juice gives an alkaline medium.
  •  It makes the food alkaline so that pancreatic enzymes can act on it as it requires alkaline or basic medium and intestinal enzymes in the small intestine.
• It activates the digestive enzymes.
• Fats are broken down by lipases with the help of bile into di-and monoglycerides.
• Jaundice is due to the deposition of bile pigments.
