How is the digestion of fats different from that of proteins and carbohydrates?

(1) Fat digestion occurs in the small intestine, and the digestion of proteins and carbohydrates occurs in the stomach

(2) Fats are absorbed into the cells as fatty acids and monoglycerides but are then modified for absorption into the blood; amino acids and glucose are not modified further

(3) Fats enter the hepatic portal circulation, but digested proteins and carbohydrates enter the lymphatic system

(4) Digested fats are absorbed in the large intestine, and digested proteins and carbohydrates are absorbed in the small intestine

The initial step in the digestion of milk in infants is carried out by?

(1) Lipase

(2) Trypsin

(3) Rennin

(4) Pepsin

Assertion      :       Hepatopancreas of prawn is equivalent to the liver and pancreas of higher animals.

Reason         :       Hepatopancreas stores the absorbed nutrients from stomach and midgut.

Assertion      :       Rumen of alimentary canal of ruminant animals harbour numerous bacteria and protozoa.

Reason         :       Bacteria and protozoa help in the secretion of gastric juice in the rumen.

Assertion      :       Many tube like glands are present in the wall of small intestine.

Reason         :       These glands secrete enzymes DNAse and RNAse into the intestinal juice.

Assertion      :       Lipases of bile help in the emulsification of fats.

Reason         :       Lipases can break large fat droplets into smaller ones.

Assertion      :       Presence of HCl in stomach is necessary for the process of digestion.

Reason         :       HCl kills and inhibits the growth of bacteria in the stomach.

Assertion      :       Facilitated diffusion is more rapid than simple diffusion.

Reason         :       Facilitated diffusion involves expenditure of energy unlike simple diffusion.

Assertion      :       Carbohydrates are more suitable for the production of energy in the body than proteins and fats.

Reason         :       Carbohydrates can be stored in the tissues as glycogen for use in the production of energy, whenever necessary.

Assertion      :       The amino acid glycine comes under the category of nonessential amino acids.

Reason         :       This is due to the fact that it can not be synthesised in the body.
