  • 3. Question 2 <ul><li>The chemical element found in all amino acids but not found in either carbohydrates or fats is </li></ul><ul><li>A. carbon. </li></ul><ul><li>B. nitrogen. </li></ul><ul><li>C. oxygen. </li></ul><ul><li>D. hydrogen. </li></ul>
  • 4. Question 3 <ul><li>Which of the following is true about protein? </li></ul><ul><li>A. It is unique in that it is the only dietary component that contains selenium. </li></ul><ul><li>B. It is important primarily for increasing bone density. </li></ul><ul><li>C. It is made up of combinations of approximately 20 amino acids. </li></ul><ul><li>D. It is made up of combinations of amino acids and fatty acids. </li></ul>
  • 5. Question 4 <ul><li>An essential amino acid </li></ul><ul><li>A. can be synthesized in the body if there is a nitrogen source. </li></ul><ul><li>B. can be synthesized in the body if caloric intake is adequate. </li></ul><ul><li>C. cannot be synthesized in the body in sufficient quantity to meet body needs. </li></ul><ul><li>D. can be formed in the body from semiessential amino acids. </li></ul>
  • 6. Question 5 <ul><li>The nitrogen from amino acid breakdown is </li></ul><ul><li>A. stored in the liver. </li></ul><ul><li>B. oxidized to carbohydrate. </li></ul><ul><li>C. converted to urea. </li></ul><ul><li>D. converted to fat. </li></ul>
  • 7. Question 6 <ul><li>All of the following are true of high quality protein except </li></ul><ul><li>A. it contains all essential amino acids. </li></ul><ul><li>B. it provides 7 kcal/g of energy. </li></ul><ul><li>C. it can support body maintenance. </li></ul><ul><li>D. it can support body growth. </li></ul>
  • 8. Question 7 <ul><li>Which of the following is not true about an incomplete protein source? </li></ul><ul><li>A. It lacks one or more essential amino acids. </li></ul><ul><li>B. It cannot support body growth and maintenance by itself. </li></ul><ul><li>C. To adequately meet protein needs from incomplete protein sources a person would have to eat two complementary proteins. </li></ul><ul><li>D. Lower quantities of this source could be eaten to get adequate quantities of essential amino acids. </li></ul>
  • 9. Question 8 <ul><li>Which of the following is a food that provides all of the essential amino acids? </li></ul><ul><li>A. Wheat </li></ul><ul><li>B. Peanut butter </li></ul><ul><li>C. Navy beans </li></ul><ul><li>D. Milk </li></ul>

  • 11. Question 10 <ul><li>What enzyme is released by the stomach to digest protein? </li></ul><ul><li>A. Pepsin </li></ul><ul><li>B. Lipoprotein lipase </li></ul><ul><li>C. Amylase </li></ul><ul><li>D. Trypsin </li></ul>
  • 12. Question 11 <ul><li>Which of the following is not true about pepsin? </li></ul><ul><li>A. Amino acid chains are the digestive products of its action. </li></ul><ul><li>B. Pepsin works best in an alkaline environment. </li></ul><ul><li>C. Acid activates pepsin. </li></ul><ul><li>D. Pepsin acts on food in the stomach. </li></ul>
  • 13. Question 12 <ul><li>If the diet is lacking an essential amino acid, what will be the course of action? </li></ul><ul><li>A. Body cells will synthesize it. </li></ul><ul><li>B. Protein synthesis will be limited. </li></ul><ul><li>C. Health will not be affected as long as other nutrients are adequate. </li></ul><ul><li>D. Proteins will be made but they will lack that particular amino acid. </li></ul>
  • 14. Question 13 <ul><li>If a food does not contain the necessary amounts of a certain amino acid to meet a body need, that amino acid is referred to as a </li></ul><ul><li>A. complementary amino acid. </li></ul><ul><li>B. essential amino acid. </li></ul><ul><li>C. limiting amino acid. </li></ul><ul><li>D. dispensable amino acid. </li></ul>
