Question

Bile juice is stored in a sac called, gall bladder, located near its organ of
secretion, 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 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 digestion of fat?
(d) Where is the digestion of fat completed?
(e) Does bile juice digest fat completely?​

Answer 1

Answer:

a gall bladder

b as fats are insoluble in water and are large globular

c by emulsify fats

d small intestine

e no

Answer 2

Answer:

(a) Liver

(b) The fats cannot be digested easily because the are insoluble in water and are present as large globules. Bile juice breaks down big fat droplets into smaller droplets.

(c) Bile is a fluid that is made and released by the liver and stored in the gall bladder. Bile helps with digestion . It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.

(d) The digestion of fat is completed in small intestine where fat gets converted into fatty acids and glycerols.

(e) Bile juice does not digest fats as it does not contain any enzymes. Instead, it contains bile salts which helps in emulsification of fats so that ezymes could act upon them efficiently.
