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, glucose Small intestine, active absorption
• B. Fructose, ${Na}^{+}$ Small intestine, passive absorption
• C. Cholesterol, maltose Large intestine, active absorption
• D. Bile acids, fatty acids Duodenum, move as chilomicrons

Answer 1

Answer: (A)

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).
