Explanation / Answer

T30 Which of the following is not a function of large intestine?

Answer:- d. Absorb chylomicrons

Explanation:- Chylomicrons are lipoproteins transport fats and not absorbed by large intestine as the major functions of the large intestine are to absorb water and electrolytes, to secrete mucus, and to form feces.

31 Choose the incorrect statement regarding bile.

Answer:- d. Bile contains enzymes for lipid digestion.

Explanation:- Bile is secreted by liver cells ( hepatocytes) is an excretory as well as digestive secretion that emulsify fats and carries bilirubin that is byproduct from breakdowns of worn out RBCs. It does not contains any enzyme for lipid digestion as it just emulsify it for easier digestion.

32 Pancreatic juice may contain which of the following?

Answer:- e. All of the above

Explanation:- pancreatic juice is a colourless liquid secreted by pancreas and comprises mostly water, sodium bicarbonate, and enzymes like amylase, trypsin, chymotrypsin, carboxypeptidase , lipase which activates normally inside the small intestine and help in digestion of food.

33 The digestion of which nutrient would be most affected if the liver stops functioning ?

Answer:- e.triglycerides

Explanation:- Liver is the largest gland of our body and mainly produce bile which emulsifies fats and make their digestion more easy. Triglycerides are types of fats and thus the digestion of it would be most affected if the liver stops functioning.

34 Which hormone causes an increased output of enzyme-rich Pancreatic juice and stimulates gallbladder concentration ?

Answer:- c. Cholecystokinin (CCK)

Explanation:- The I cells of the duodenum and proximal jejunum secretes cholecystokinin hormone. This hormone stimulates enzyme secretion from pancreas and contraction of gall bladder.

35 Carbohydrates are completely digested to _____________ before they are absorbed.

Answer:- b. Monosaccharides

Explanation:- carbohydrates are macronutrients and made up of polysaccharides which are completely digested to monosaccharides by Pancreatic amylase enzyme inside the small intestine before they are absorbed.
