1. Which types of acids form the basic building blocks of protein?
- A. fatty
- B. amino
- C. nucleic
- D. omega fatty
Correct answer: B
Rationale: The correct answer is 'B: amino.' Amino acids are the fundamental units that make up proteins. They are essential for various bodily functions, including building and repairing tissues. Choice A, 'fatty acids,' are not the basic building blocks of proteins but rather a type of lipid. Choice C, 'nucleic acids,' are the building blocks of nucleic acids like DNA and RNA, not proteins. Choice D, 'omega fatty acids,' are a specific type of fatty acid known for their health benefits but are not directly related to the building blocks of proteins.
2. What is the recommended dietary intake of protein for adults?
- A. 0.5 g/kg.
- B. 0.8 g/kg.
- C. 1.0 g/kg.
- D. 1.5 g/kg.
Correct answer: B
Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.
3. What is the primary nutritional function of the large intestine?
- A. Absorption of fats.
- B. Excretion of waste products.
- C. Excretion of bacteria.
- D. Absorption of water.
Correct answer: D
Rationale: The correct answer is D: Absorption of water. The primary nutritional function of the large intestine is to absorb water from the indigestible food residue that enters it from the small intestine. This absorption of water helps to form solid waste, which is then eliminated from the body. Choices A, B, and C are incorrect because the large intestine is not primarily responsible for the absorption of fats, excretion of waste products, or excretion of bacteria. While the large intestine does play a role in waste elimination and contains bacteria beneficial for digestion, its main function in terms of nutrition is the absorption of water.
4. Two amino acids are chemically joined by a:
- A. double bond.
- B. hydrogen bond.
- C. carboxyl bond.
- D. peptide bond.
Correct answer: D
Rationale: The correct answer is D, peptide bond. A peptide bond is formed through a dehydration synthesis reaction between the amine group of one amino acid and the carboxyl group of another amino acid. This bond is crucial in protein synthesis. Choices A, B, and C are incorrect. A double bond involves sharing two pairs of electrons, a hydrogen bond is a weak attraction between a hydrogen atom and an electronegative atom, and a carboxyl bond is not a common term in biochemistry.
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.
