Question

Mechanism for absorption of fats in small intestine

Accepted Answer

• When a micelle comes into contact with the epithelial cells of small intestine, the contents pass by means of *simple diffusion* into the cell

• Inside the cell, glycerol and fatty acids are recombined into fats and packaged into chylomicrons.

• The chylomicrons are transported by exocytosis into lacteals.
