Question

Read the following passage carefully and answer the questions that follow it. Bile juice is stored in a sac called, gallbladder, located near its organ of secretion, the liver. The gallbladder 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 from the pancreas.

(a) Which organ secretes the bile juice?
(b) Why is digestion of fats difficult as compared to that of other nutrients?
(c) How does bile juice help in the digestion of fat?
(d) Where is the digestion of fat completed?
(e) Does bile juice digest fat completely?
