  2. B
    Chylomicrons are small lipoprotein particles that are transported from intestine into blood capillaries.
  3. C
    About of starch is hydrolysed by salivary amylase in our mouth.
  4. D
    Oxyntic cells in our stomach secrete the proenzyme pepsinogen.

Solution & Step-by-step Explanation

Fructose is absorbed via facilitated diffusion. Certain amino acids and glucose are absorbed via active transport using carrier ions.Salivary amylase only hydrolyzes about of starch.Oxyntic (parietal) cells secrete ; Peptic (chief) cells secrete pepsinogen.
