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

    A)
    Column-I Column-II
    Glycine and glucose Small intestine and active absorption

    B)
    Column-I Column-II
    Fructose and \[N{{a}^{+}}\] Small intestine passive absorption

    C)
    Column-I Column-II
    Glycerol and fatty acids Duodenum and move as chylomicrons

    D)
    Column-I Column-II
    Cholesterol and maltose Large intestine and active absorption

    Correct Answer: A

    Solution :

     Amino acids monosaccharides like glucose, electrolytes like \[\text{N}{{\text{a}}^{\text{+}}}\]are absorbed into the blood by active transport. Fructose and some amino acids are absorbed with the help of the carrier ions like \[\text{N}{{\text{a}}^{\text{+}}}\]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.
