Difficulty: Hard

Learning Objective 1: 6.3 Describe the digestion and absorption of proteins.

Learning Objective 2: 6.3.2 Discuss how amino acids are absorbed.

Solution: Amino acids with similar structures use the same transport system to cross the lumen of the small intestine. As a result, amino acids that use the same transport system may compete with one another for absorption. If there is an excess of any one of the amino acids sharing a transport system, more of it will be absorbed, slowing the absorption of competing amino acids and upsetting the balance of amino acids in the body.

Learning Objective 2: 6.4.3 Name the four functions of body proteins.

Section Reference 1: Section 6.4 Protein Synthesis and Functions

Solution: Skin, which is made primarily of protein, is the first barrier against infection and injury and if a foreign material gets in to the body, antibodies, which are immune system protein, help destroy it. Blood proteins contribute to the number of dissolved particles in the blood. If protein levels in the blood fall too low, osmosis causes fluid to leak out of the blood vessels and accumulate in the tissue, causing edema. Protein also regulates fluid balance because some are membrane transporters, which pump dissolved substances from one side of a membrane to the other.

Use the following terms in your response: essential amino acids, incomplete dietary protein, high quality protein, protein complementation. Is it necessary to eat the rice and beans at the same meal?

 

Answer:

 

Difficulty: Medium

Learning Objective 1: 6.6 Discuss healthy ways to meet the protein needs of the body.

Learning Objective 2: 6.6.3 Review a diet and replace the animal proteins with complementary plant proteins.

Section Reference 1: Section 6.6 Meeting Protein Needs

Solution: Plant proteins are lower in one or more of the essential amino acids, and are therefore referred to as incomplete dietary protein sources. When rice, which is limited in lysine but high in methionine, is eaten with beans, which are high in lysine but limited in methionine, are combined, the essential amino acids are provided in the amounts needed by the body. The process of combining proteins from different sources so that they collectively provide the proportions of essential amino acids required to meet the bodys needs is called protein complementation. Complementary proteins do not have to be consumed in the same meal.
