Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Absorption of amino acids
Concept:

Nutrient absorption is highly compartmentalized in the human digestive system.

Formula:

N/A

Solution:

  • The primary role of the small intestine is to completely digest and absorb macronutrients (carbohydrates, fats, amino acids).
  • By the time chyme reaches the large intestine, practically all amino acids and glucose have already been extracted into the bloodstream.
  • The large intestine's main role is to absorb remaining water and electrolytes, and house bacteria that produce vitamins (like Vitamin K).


Why other options are incorrect:

Water and electrolyte absorption, alongside hosting vitamin-producing bacteria, are the exact physiological purposes of the large intestine.
