Select the correct match of the digested products in humans given in column I with their absorption site and mechanism in column II
Answers
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: A
Glycine, glucose Small intestine, active absorption
Explanation:
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).
