1. 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.

2. The valve that controls the passage of chyme from the small intestine into the cecum is called the:

A. ileocecal valve.
B. pyloric valve.
C. cardiac valve.
D. hepatic valve.

Correct answer: A

Rationale: The correct answer is A: ileocecal valve. The ileocecal valve is located between the small intestine and the cecum, controlling the passage of chyme. The pyloric valve (choice B) is located between the stomach and the small intestine, regulating the passage of food from the stomach to the small intestine. The cardiac valve (choice C) refers to the valve between the esophagus and the stomach. The hepatic valve (choice D) is not a correct term related to the passage of chyme from the small intestine into the cecum.

3. Which of the following is a characteristic of essential fatty acids?

A. They can come from both animal and plant sources.
B. They are not manufactured by the body.
C. They are not manufactured by the body.
D. They are manufactured by the body.

Correct answer: B

Rationale: The correct answer is B: Essential fatty acids are not manufactured by the body. These fatty acids must be obtained through the diet because the body cannot synthesize them. Choice A is incorrect because essential fatty acids can come from both animal and plant sources, not just from an animal source. Choice C is the correct characteristic of essential fatty acids. Choice D is incorrect because essential fatty acids are not produced by the body.

4. Which of the following foods is high in indispensable amino acids?

A. Lentils
B. Tofu
C. Peanuts
D. Eggs

Correct answer: D

Rationale: The correct answer is D, eggs. Eggs are considered a high-quality protein source as they are rich in indispensable amino acids. Lentils, tofu, and peanuts also contain protein but are not as high in indispensable amino acids as eggs, making them less complete protein sources.

5. What is the term for the production of glucose from protein, lactate, or glycerol?

A. glycolysis
B. gluconeogenesis
C. glycogenolysis
D. glucogenesis

Correct answer: B

Rationale: Gluconeogenesis is the correct term for the production of glucose from non-carbohydrate sources such as protein, lactate, or glycerol. Choice A, glycolysis, is the process of breaking down glucose into pyruvate. Choice C, glycogenolysis, is the breakdown of glycogen into glucose. Choice D, glucogenesis, is not a recognized term in biochemistry.
