Exam 6: Proteins and Amino Acids

A ____ excludes all animal flesh except fish.

Plant proteins are referred to as incomplete dietary protein.

Endurance and strength athletes have a greater protein daily recommendation than non-athletes; therefore, they must use amino acid supplements.

In general, plant sources of protein provide _____absorbable forms of iron, zinc, and calcium as compared to animal protein sources.

Nekesa is considering taking a nutrition supplement of the amino acid arginine. Considering what you know about the absorption of amino acids, why would you caution her against this?

When your diet is high in iron, the gene that codes for the protein ferritin, which stores iron, is turned on. This scenario best describes which of the following processes?

For some of the amino acids that our body needs, we must get them from dietary sources because the body cannot make them in sufficient quantities to meet our body's needs.

The order and chemical properties of _____ in a polypeptide chain determine how the polypeptide fold, and thus the shape of the molecule formed.

Protein and amino acid supplements are rarely needed to increase protein needs.

Review where digestive processes of protein occur. Select the letter that indicates where Pepsin begins the chemical digestion of protein.

There are certain conditions under which some of the nonessential amino acids cannot be synthesized to meet the body's needs. When this occurs these amino acids are referred to as ____ amino acids.

If the diet is deficient in one or more of the _____amino acids, the body must break down existing proteins to provide the amino acids.

The amino acid pool is comprised of the

Marasmus is a form of malnutrition that negatively impacts which of the following developing organs the worst?

Rice is high in the amino acids methionine but low in the amino acid lysine. Beans are high in lysine but low in methionine. Explain why eating rice and beans together increases the protein quality of a meal, as compared to eating a vegetarian meal that contains rice and no beans. 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?

Kwashiorkor is an overall energy deficiency whereas marasmus is a protein deficiency.

What is the condition called that is depicted in this photograph? SPL/Photo Researchers, Inc.

A diet that is based on plant proteins alone cannot meet most people's protein needs.

The process by which amino acids enter the body involves an energy-requiring amino acid transport system.

The shape of a protein is essential to its function.
