1. Which of the following is an example of a complete protein?

• A. Milk
• B. Soy
• C. Sesame seeds
• D. Sweet potato

Correct answer: A

Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.

2. An example of government nutrition policy is:

• A. MyPlate Food Guidance System.
• B. Dietary Guidelines for Americans 2010.
• C. Healthy People 2020.
• D. Dietary Reference Intakes (DRIs).

Correct answer: C

Rationale: The correct answer is C: Healthy People 2020. Healthy People 2020 is a government initiative that sets goals for improving the health of Americans, including specific nutritional objectives. Choices A, B, and D are not examples of government nutrition policies. MyPlate Food Guidance System is a visual tool to help individuals make healthy food choices, Dietary Guidelines for Americans 2010 provide evidence-based advice for Americans two years and older, and Dietary Reference Intakes (DRIs) are a set of nutrient reference values.

3. From where are trypsin and chymotrypsin secreted?

• A. Small intestine.
• B. Liver.
• C. Stomach.
• D. Pancreas.

Correct answer: D

Rationale: Trypsin and chymotrypsin are enzymes involved in protein digestion. These enzymes are secreted by the pancreas, not the small intestine, liver, or stomach. The pancreas plays a crucial role in producing digestive enzymes that aid in breaking down proteins in the small intestine. The small intestine is the site where these enzymes act, not where they are secreted. The liver is responsible for producing bile, not digestive enzymes. The stomach secretes gastric juices but not trypsin and chymotrypsin. Therefore, the correct answer is the pancreas.

4. For a healthy person, what percentage of daily calories should be supplied by protein?

• A. 5% to 10%.
• B. 10% to 35%.
• C. more than 25%.
• D. more than 35%.

Correct answer: B

Rationale: The correct answer is B: 10% to 35%. For a healthy person, it is recommended that 10% to 35% of their daily caloric intake should come from protein. This range ensures an adequate intake of protein for various bodily functions without overdoing it. Choices A, C, and D are incorrect because they suggest percentages either below the recommended range (A, C) or exceeding it (D), which could lead to nutritional imbalances or health issues.

5. What are dextrins?

• A. Polysaccharides.
• B. End products of starch digestion.
• C. Formed in the liver.
• D. Rapidly excreted.

Correct answer: A

Rationale: Dextrins are a type of polysaccharides formed during the breakdown of starch. Choice A is correct because dextrins are indeed polysaccharides, not the end products of starch digestion (Choice B). They are not formed in the liver (Choice C) nor rapidly excreted (Choice D).
