Question

The enzyme lipoprotein lipase enables chylomicra to:

a. reduce the level of harmful cholesterol in the blood.
b. deliver their dietary fatty acids to cells.
c. digest triglycerides in the mouth.
d. synthesize bile acid in the small intestine.

Answer 1

Lipoprotein lipase allows chylomicrons to deliver their dietary fatty acids to cells in the body, which are then used for energy or stored as fat. Correct option is b)

Step-by-step explanation:

The enzyme lipoprotein lipase plays a critical role in the metabolism of lipids after their initial digestion. Chylomicrons are water-soluble lipoproteins formed in the intestinal cells that transport dietary lipids, such as triglycerides, cholesterol, and other fats, through the lymphatic and circulatory systems to various tissues in the body. Lipoprotein lipase acts on these chylomicrons once they are in the bloodstream, breaking down the triglycerides into free fatty acids and glycerol. These fatty acids and glycerol are then taken up by cells, either to be used for energy or stored as fat in adipose tissue.

In summary, the correct answer to the student's question is: b. deliver their dietary fatty acids to cells. This process enables the transport and eventual uptake of dietary fats that have been packaged into chylomicrons within the aqueous environment of the body's fluids.
