D.  triglycerides

Clarify Question
· What is the key concept addressed by the question?
        o The question asks about what chylomicrons contain.
· What type of thinking is required?
        o You are being asked to apply your knowledge about what chylomicrons contain.

· What do you know about what chylomicrons contain? What other information is related to the question?
        o Fats (triglycerides) are hydrolyzed into fatty acids and monoglycerides by digestion. These fatty acids and monoglycerides are nonpolar and can thus enter epithelial cells by simple diffusion. Once inside the intestinal epithelial cells they are reassembled into triglycerides. The triglycerides then combine with proteins to form small particles called chylomicrons, which are too bulky to enter blood capillaries in the intestine. Instead of entering the hepatic portal circulation, the chylomicrons are absorbed into lymphatic capillaries, which empty their contents into the blood in veins near the neck.

· Given what you now know, what information is most likely to produce the correct answer?
        o Chylomicrons transport dietary fats absorbed from the intestines. If you eat more triglycerides you will produce more chylomicrons that will be transported through lymphatic capillaries.

Reflect on Process
· Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
        o This question asked you to apply. If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you think that proteins were transported on chylomicrons? Did you think that sugars were transported on chylomicrons?
