Question

Select the correct match of the digested products in humans given in colum I with their absorption site and
mechanism in column II.

• A.

  	Column I	Column II
  (1)	Glycine, glucose	small intestine, active

• B.

  	Column I	Column II
  (2)	Fructose, $N{a}^{+}$	small intestine, passive absorption

• C.

  	Column I	Column II
  (3)	Glycerol, fatty acids	duodenum, move as chilomicrons

• D.

  	Column I	Column II
  (4)	Cholesterol, maltose	large intestine, active absorption

Answer 1

The correct option is A

	Column I	Column II
(1)	Glycine, glucose	small intestine, active

Various nutrients like amino acids, glucose, electrolytes like $N{a}^{+}$ are absorbed into the blood by Active transport.

The small intestine is the principal organ for absorption of nutrients. Amino acids like glycine, monosaccharides like glucose absorbed into the blood by active absorption.

Fructose is absorbed by facilitated absorption while Na+ is by active absorption in the small intestine. Bile acids are absorbed in ileum region by active absorption. Fatty acids, cholesterol are absorbed as chylomicrons by lacteals and then drain into bloodstream.

Maltose is broken down into glucose by maltase then that glucose is absorbed by simple diffusion in the small intestine.

So, the right option is (A).
