Micelles

Question 1

Formation

Answer 1

After larger, lipid molecules have been broken down into monoglycerides and fatty acids, bile salts are secreted by the liver.

The bile salts associate with the monoglycerides and fatty acids to form micelles.

Micelles are circular formations that are made up of phospholipid tails.

Question 2

Incorporation

Answer 2

The micelles move through the ileum and come into contact with the epithelial cells.

The micelles incorporate themselves into the epithelial cell surface membrane and are absorbed.
