Dear student

The solutions to 1, 2 queries have been provided below:

1.

The raw materials for photosynthesis are carbon dioxide, water, sunlight and chlorophyll.

2.

Bile juice is a digestive juice secreted by the liver. Although it does not contain any digestive enzymes, it plays an important role in the digestion of fats. Bile juice has bile salts such as bilirubin and biliverdin. These break down large fat globules into smaller globules in the small intestine so that the pancreatic enzymes can easily act on them. This process is known as emulsification of fats. Bile juice also makes the medium alkaline and activates lipase.

For remaining queries we request you to post them in separate threads to have rapid assistance from our experts.

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.

(a) Which organ secretes the bile juice?

(b) Why is digestion of fats difficult as compared to that of other nutrients?

(d) Where is the digestion of fat completed?

(e) Does bile juice digest fat completely?
