Question

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

column I	column II
(a) Glycine and glucose	1. Small intestine and active absorption
(b) Fructose and Na+	2. Small intestine passive aborption
(c) Glycerol and fatty acids	3. Duodenum and move as chilomicrons
(d) Cholesterol and maltose	4. Large intestine and active absorption

Answer 1

Correct option (a)

Explanation :

Amino acids, monosaccharides like glucose, electrolytes like Na⁺ are absorbed into the blood by active transport. Fructose and some amino acids are absorbed with the help of the carrier ions like Na⁺  by facilitated transport.

Fatty acid and glycerol cannot be absorbed into the blood. They are first incorporated into small droplets called micelles, which move into the intestinal mucosa.
