1. Major nutrients supplied by foods in the Vegetables group of MyPlate include:
- A. potassium and vitamin A.
- B. iron and vitamin C.
- C. calcium and vitamin B12.
- D. sodium and vitamin E.
Correct answer: A
Rationale: The correct answer is A: potassium and vitamin A. Vegetables are an excellent source of potassium and vitamin A, both essential for maintaining overall health. Iron and vitamin C (choice B) are commonly found in foods from the Protein and Fruits groups, respectively. Calcium and vitamin B12 (choice C) are more abundant in dairy products and animal-based foods. Sodium and vitamin E (choice D) are not the major nutrients typically supplied by vegetables.
2. 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.
3. Which of the following is an example of a protein?
- A. Saline.
- B. Hemoglobin.
- C. Cellulose.
- D. Prostaglandins.
Correct answer: B
Rationale: Hemoglobin is a protein that carries oxygen in the blood, making it the correct answer. Choice A, Saline, is a salt solution and not a protein. Choice C, Cellulose, is a complex carbohydrate found in the cell walls of plants, not a protein. Choice D, Prostaglandins, are lipid compounds with hormone-like effects, not proteins.
4. Which of the following enzymes is found in pancreatic secretions?
- A. Rennin
- B. Pepsin
- C. Chymotrypsin
- D. Casein
Correct answer: C
Rationale: Chymotrypsin is an enzyme found in pancreatic secretions that plays a role in protein digestion. Rennin is primarily found in the stomach and is involved in milk digestion. Pepsin is also a stomach enzyme that aids in protein breakdown. Casein is a protein found in milk, not an enzyme involved in pancreatic secretions. Therefore, the correct answer is Chymotrypsin.
5. Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?
- A. Fructose.
- B. Galactose.
- C. Sucrose.
- D. Maltose.
Correct answer: B
Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk. Fructose is a monosaccharide found in fruits and honey. Sucrose is a disaccharide composed of glucose and fructose, commonly known as table sugar. Maltose is a disaccharide formed by the combination of two glucose molecules.
