1. A protein that contains all the essential amino acids in the proper proportions is called:

• A. simple
• B. indispensable
• C. complete
• D. complementary

Correct answer: C

Rationale: A complete protein is the term used to describe a protein that contains all the essential amino acids required by the body in the right proportions. This makes choice C the correct answer. Choice A, 'simple,' is incorrect as it does not reflect the concept of essential amino acids. Choice B, 'indispensable,' while related to importance, does not specifically address the presence of all essential amino acids. Choice D, 'complementary,' is also incorrect as it refers to combining proteins to achieve a complete amino acid profile, rather than describing a protein that already contains all essential amino acids.

2. What is the main body storage form of carbohydrates?

• A. Glycogen.
• B. Starch.
• C. Fat.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A: Glycogen. Glycogen is the stored form of carbohydrates in the body, primarily found in the liver and muscles. Starch (choice B) is a carbohydrate storage molecule in plants, not in the human body. Fat (choice C) is a different macronutrient and not the main storage form of carbohydrates. Glucose (choice D) is a simple sugar that serves as an energy source, not the main storage form of carbohydrates.

3. People with phenylketonuria should avoid foods made with which nonnutritive sweetener?

• A. acesulfame-K
• B. aspartame
• C. saccharin
• D. sucralose

Correct answer: B

Rationale: People with phenylketonuria should avoid aspartame because it contains phenylalanine, which they cannot metabolize. Acesulfame-K, saccharin, and sucralose do not contain phenylalanine and are safe for individuals with phenylketonuria. Therefore, the correct answer is B. Acesulfame-K, saccharin, and sucralose are incorrect choices because they do not pose a risk for individuals with phenylketonuria due to the absence of phenylalanine in their composition.

4. What triggers the release of cholecystokinin (CCK)?

• A. Presence of food in the stomach.
• B. Presence of fat in the duodenum.
• C. Entry of acid chyme into the ileum.
• D. Entry of bile into the gallbladder.

Correct answer: B

Rationale: The correct answer is B: Presence of fat in the duodenum. Cholecystokinin (CCK) is released in response to the presence of fat in the duodenum to aid in digestion by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Options A, C, and D are incorrect because CCK is specifically released in response to the presence of fat in the duodenum, not food in the stomach, acid chyme in the ileum, or bile in the gallbladder.

5. 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.
