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

• A. 1 tbsp peanut butter.
• B. 3 oz fish.
• C. 2 oz cheese.
• D. 1/2 cup cooked dry beans or peas.

Correct answer: A

Rationale: One tablespoon of peanut butter is equivalent to one serving from the Protein group in MyPlate. It provides a good amount of protein and healthy fats. Choices B, C, and D are incorrect as they represent larger serving sizes than a single serving from the Protein group in MyPlate. 3 oz of fish, 2 oz of cheese, and 1/2 cup of cooked dry beans or peas would exceed the recommended serving size for the Protein group.

2. Consuming 30 g of which nutrient would provide the highest number of kcalories?

• A. Carbohydrates
• B. Fat
• C. Protein
• D. Micronutrients

Correct answer: B

Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.

3. Where does gluconeogenesis occur?

• A. Muscles.
• B. Pancreas.
• C. Liver.
• D. Spleen.

Correct answer: C

Rationale: Gluconeogenesis mainly occurs in the liver. It is a process where glucose is synthesized from non-carbohydrate sources such as amino acids and glycerol. The liver is the primary site for gluconeogenesis due to the presence of key enzymes and substrates required for this process. Muscles do not play a significant role in gluconeogenesis, making choice A incorrect. The pancreas is involved in the regulation of blood sugar levels through insulin and glucagon but is not the primary site for gluconeogenesis, so choice B is incorrect. The spleen is not a major organ involved in glucose metabolism, making choice D incorrect.

4. How many kilocalories are provided by 15 grams of protein?

• A. 15
• B. 45
• C. 60
• D. 135

Correct answer: C

Rationale: Protein provides 4 kcal per gram. Therefore, 15 grams of protein will provide 15 grams x 4 kcal/gram = 60 kcal. Choices A, B, and D are incorrect because they do not consider the caloric value of protein correctly.

5. Ketones are produced when:

• A. carbohydrate stores are depleted.
• B. excess protein is consumed.
• C. protein stores are depleted.
• D. fat stores are depleted.

Correct answer: A

Rationale: Ketones are produced when the body uses fat for energy due to the depletion of carbohydrate stores. When carbohydrate stores are depleted, the body turns to fat as its primary source of energy, leading to the production of ketones. Excess protein consumption does not directly lead to ketone production. Similarly, the depletion of protein stores or fat stores is not directly related to the production of ketones.
