Question

Choose the molecule that is correctly tied to its digestion or function.

		Monoglycerides and fatty acids: Digestion would be impacted by brush border destruction.
		Micelles: Reformed within the epithelial cells of small intestine.
		Protease: Essential for hydrolysis of triglycerides.
		Bile salts: Enter lacteal.
		Calcitriol: Absorption of iron.

Answer 1

Micelles - Reformed within the epithelial cells of small intestine, this statement is correctly matched.

Micelles are small aggregates of mixed lipids and bile acids. The are 4-8 nanometer in diameter. The micelles are transported to the brush borders of the small intestine absorptive cells . Further the long chain fatty acid and monoglyceride diffuse out of the micelles into the absorptive cell leaving the micelle behind in the chyme.

Rest all the options are incorrect as monoglycerides are emulsifiers , protease are enzyme which catalyze proteolysis, bile salts dont enter lacteal and calcitriol regulates mainly calcium and phosphorus.
