1. A food choice equivalent to one serving from the Grains group of MyPlate is:

• A. one slice of bread
• B. 2 cups of rice
• C. 3 cups of spaghetti
• D. 4 oz of ready-to-eat cereal

Correct answer: A

Rationale: One slice of bread is a standard serving from the Grains group in MyPlate. This choice aligns with the recommended portion size for grains. Choices B, C, and D are excessive portions that do not represent a single serving according to MyPlate guidelines. 2 cups of rice, 3 cups of spaghetti, and 4 oz of ready-to-eat cereal exceed the standard serving size for grains and would provide more than one serving from this food group.

2. During the process of deamination, the nitrogen portion of amino acids is converted to:

• A. ammonia.
• B. protein.
• C. purines.
• D. glycogen.

Correct answer: A

Rationale: During the process of deamination, the nitrogen portion of amino acids is converted to ammonia. This occurs in the liver as part of the process to remove excess nitrogen from the body. Choice B, 'protein,' is incorrect as deamination breaks down amino acids rather than synthesizing proteins. Choice C, 'purines,' is incorrect as purines are a type of nitrogenous base found in DNA and RNA, not a product of deamination. Choice D, 'glycogen,' is incorrect as glycogen is a storage form of glucose and not a product of amino acid deamination.

3. What is the basis of MyPlate food guidance?

• A. Percentage of calories from each macronutrient.
• B. Exchange Lists for Meal Planning.
• C. Appropriate amounts of food from each food group.
• D. Amounts of macronutrients and micronutrients.

Correct answer: C

Rationale: The correct answer is C: 'Appropriate amounts of food from each food group.' MyPlate food guidance focuses on portion sizes from different food groups to promote a balanced diet. Choices A, B, and D are incorrect because MyPlate emphasizes the consumption of a variety of foods from different food groups rather than focusing solely on macronutrient percentages, exchange lists, or specific nutrient amounts.

4. Which hormone prevents excessive gastric activity?

• A. Gastrin
• B. Enterogastrone
• C. Secretin
• D. Cholecystokinin

Correct answer: B

Rationale: The correct answer is Enterogastrone. Enterogastrone is a hormone that inhibits excessive gastric activity by slowing down stomach contractions and emptying. Gastrin (choice A) stimulates gastric acid secretion, secretin (choice C) regulates pH levels in the duodenum, and cholecystokinin (choice D) stimulates the release of digestive enzymes and bile.

5. Which term describes the amino acids that are synthesized by the body?

• A. essential amino acids.
• B. nonessential amino acids.
• C. complete amino acids.
• D. incomplete amino acids.

Correct answer: B

Rationale: The correct answer is B: nonessential amino acids. Nonessential amino acids can be synthesized by the body, so they do not need to be obtained through the diet. Essential amino acids, choice A, must be obtained from the diet because the body cannot produce them. Choices C and D, complete and incomplete amino acids respectively, do not accurately describe the classification of amino acids based on synthesis by the body.
