6.9 (2) Digestion of lipids Flashcards
1
Q
how is the micelle absorbed into the epithelial cell?
A
- collides with the epithelial cell
- releases monoglycerides and the fatty acids
2
Q
how does the monoglyceride and fatty acids enter the epithelial cell?
A
diffuses through the phospholipid bilayer
- as they are lipid soluble
3
Q
what happens to the monoglyceride and fatty acids inside the epithelial cells?
A
passes through the SER
- turns back into micelle
passes through golgi apparatus
- turns into chylomicron
4
Q
what is inside the chylomicron?
A
cholesterol
lipoprotein
lipid
5
Q
how does the chylomicron leave the epithelial cell?
A
exocytosis
6
Q
where does the chylomicron go after leaving the epithelial cell?
A
into the lacteal
7
Q
what happens after the chylomicron enter the lacteal?
A
- enters the capillary
- chylomicron hydrolysed by enzyme on the endothelium
- the monoglyceride and the fatty acids enter the cells
8
Q
what is the lacteal part of?
A
part of the lymphatic capillary
