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.

Which of the following is an example of a disaccharide?

  • A. Glucose.
  • B. Fructose.
  • C. Galactose.
  • D. Maltose.

How can cholesterol absorption be decreased?

  • A. Vitamin K.
  • B. Plant sterols.
  • C. Trans fats.
  • D. Phospholipids.
Correct Answer: B

Rationale: The correct answer is B: Plant sterols. Plant sterols can reduce cholesterol absorption by competing with cholesterol for absorption sites. Vitamin K, choice A, does not have a significant impact on cholesterol absorption. Trans fats, choice C, are known to increase cholesterol levels rather than decrease absorption. Phospholipids, choice D, play a role in cell structure and are not directly involved in reducing cholesterol absorption.

Which gastric enzyme present in infants coagulates milk?

  • A. Casein.
  • B. Pepsinogen.
  • C. Trypsin.
  • D. Rennin.
Correct Answer: D

Rationale: The correct answer is D, rennin. Rennin is the enzyme in infants responsible for coagulating milk, which aids in the digestion process. Choice A, casein, is a milk protein and not an enzyme. Choices B and C, pepsinogen and trypsin, are digestive enzymes but are not specifically involved in coagulating milk in infants.

A vegetarian diet that includes dairy foods and eggs is known as:

  • A. lactovegetarian.
  • B. vegan.
  • C. semi-vegetarian.
  • D. ovolactovegetarian.
Correct Answer: D

Rationale: The correct term for a vegetarian diet that includes both dairy foods and eggs is 'ovolactovegetarian.' This term specifically indicates the inclusion of eggs ('ovo') and dairy ('lacto') in the diet. Choice A, 'lactovegetarian,' is incorrect because it only includes dairy products without eggs. Choice B, 'vegan,' is incorrect as it excludes all animal products, including dairy and eggs. Choice C, 'semi-vegetarian,' is incorrect as it is a term used for individuals who occasionally eat meat, poultry, or fish but primarily follow a plant-based diet.

Which tissue has the highest rate of protein turnover?

  • A. Skin
  • B. Intestinal mucosa
  • C. Muscle
  • D. Adipose tissue
Correct Answer: B

Rationale: The correct answer is B: Intestinal mucosa. The intestinal mucosa has the highest rate of protein turnover due to its rapid cell renewal. The skin, muscle, and adipose tissue do not exhibit protein turnover rates as high as the intestinal mucosa. Skin cells turnover relatively slower compared to the rapid renewal of intestinal mucosa cells. Muscles have a moderate rate of protein turnover, while adipose tissue has a lower turnover rate compared to the other tissues mentioned.
