For each scenario below, choose the most appropriate answer from the list above. Each option may be used once, more than once or not at all.

 

1. This activates LPL, causing hydrolysis of the VLDL particle and the release of glycerol and fatty acids. 

 

 

2. Epithelial cells lining the small intestine readily absorb lipids from the diet. These lipids, including triglycerides, phospholipids, and cholesterol, are assembled with apolipoprotein B-48 into what?

 

 

3.  Via apolipoprotein C-II, mature chylomicrons activate which enzyme on endothelial cells lining the blood vessels?

 

 

4. Glycerol and what can be absorbed in peripheral tissues, especially adipose and muscle, for energy and storage?

 

 

5.  The liver in the endogenous pathway is mainly the source of which type of lipoprotein?
