Solution

The correct option is A Emulsify fats for digestion
Secretion and synthesis of bile is the main function of liver. Bile is yellowish- green, alkaline fluid. In bile juice, bile sails, sodium carbonate, glycolate, taurocholate, bile pigments, cholesterol, lecithin etc. are present. Bile salts help in emulsification of fats. Bile prevents the food from decomposition, it kills the harmful bacteria. The lipase acts on emulsified fat and convert it into fatty acid and glycerol.

Question 27
Read the following passage carefully and answer the questions that follows it.

Bile juice is stored in a sac called the gall bladder, located near its organ of secretion that is the liver. The gall bladder releases the bile juice into the small intestine whenever food reaches there. Though bile juice is devoid of any digestive enzymes, it is required for the digestion of fats. The fats cannot be digested easily because they are insoluble in water and are present as large globules. Bile juice breaks down big fat droplets into smaller droplets. These are then easily digested by the enzymes released by the pancreas.
