In an analysis of the amino acid composition of foods, the amino acid occurring in the smallest amount is called:
- A. indispensable.
- B. dispensable.
- C. complementary.
- D. limiting.
Correct Answer: D
Rationale: The correct answer is D, 'limiting.' In the analysis of the amino acid composition of foods, the amino acid that occurs in the smallest amount is referred to as the limiting amino acid. This term is used because when one essential amino acid is deficient, it limits the synthesis of proteins, making it crucial in determining protein quality. Choices A, B, and C are incorrect. 'Indispensable' and 'dispensable' refer to the essentiality of amino acids, and 'complementary' does not describe the concept of the amino acid occurring in the smallest amount.
What can excessive intakes of dietary protein do?
- A. cause vitamin deficiencies.
- B. impair kidney function.
- C. increase weight loss.
- D. decrease production of indispensable amino acids.
Correct Answer: B
Rationale: Excessive intake of dietary protein can lead to impaired kidney function over time. Excessive protein consumption can put a strain on the kidneys as they work to eliminate the byproducts of protein metabolism. This can potentially lead to kidney damage. Choices A, C, and D are incorrect. Excessive protein intake is not directly linked to causing vitamin deficiencies, increasing weight loss, or decreasing the production of indispensable amino acids.
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.
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.
Which of the following is an example of a disaccharide?
- A. Glucose.
- B. Fructose.
- C. Galactose.
- D. Maltose.
