NEET 2013 Biology question

Not in NEET syllabus

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

(1)Glycine, glucose; small intestine, activeCorrect
(2)Fructose, Na; small intestine, passive absorption
(3)Glycerol, fatty acids; duodenum, move as chilomicrons
(4)Cholesterol, maltose; large intestine, active absorption

Answer: (1)

Solution

Absorption of digested products takes place mainly in the small intestine (jejunum and ileum, which have villi). Amino acids (e.g. glycine), glucose and electrolytes such as Na+ are absorbed by active transport (glucose and amino acids by Na+-linked co-transport). So (1) is correct. (2) wrong: fructose is absorbed by
