What group makes each amino acid unique?
- A. Radical group
- B. Amino group
- C. Carboxyl group
- D. Peptide bond
Correct Answer: A
Rationale: The correct answer is the radical group (R-group) because it is the unique side chain that differentiates each amino acid. The amino group (choice B) and carboxyl group (choice C) are functional groups common to all amino acids but do not make them unique. The peptide bond (choice D) is the bond formed between amino acids in a protein chain, not the group that makes each amino acid unique.
What are dextrins?
- A. Polysaccharides.
- B. End products of starch digestion.

How many amino acids are considered indispensable or essential?
- A. 9
- B. 10
- C. 12
- D. 14
Correct Answer: A
Rationale: The correct answer is A: 9. Nine amino acids are considered essential or indispensable because they cannot be synthesized by the body and must be obtained through the diet. These amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices B, C, and D are incorrect as the number of essential amino acids is specifically 9, as they are crucial for various bodily functions.
Proteins from plant sources such as grains, nuts, and legumes are classified as:
- A. incomplete.
- B. complete.
- C. indispensable.
- D. dispensable.
Correct Answer: A
Rationale: The correct answer is A: 'incomplete.' Proteins from plant sources like grains, nuts, and legumes are considered incomplete because they often lack one or more essential amino acids required by the body. Choice B, 'complete,' is incorrect because complete proteins contain all essential amino acids in adequate amounts. Choice C, 'indispensable,' is incorrect as it refers to essential amino acids rather than the classification of plant proteins. Choice D, 'dispensable,' is also incorrect as it implies that these proteins are not necessary, which is not the case.
Which phase of metabolism makes growth and repair possible?
- A. digestion
- B. catabolism
- C. anabolism
- D. ketosis
Correct Answer: C
Rationale: Anabolism is the phase of metabolism responsible for building up and repairing tissues in the body. It involves processes that require energy to synthesize complex molecules from simpler ones. Digestion (choice A) is the process of breaking down food into simpler substances for absorption. Catabolism (choice B) involves the breakdown of complex molecules into simpler ones with the release of energy. Ketosis (choice D) is a metabolic state where the body uses fat as the primary source of energy, which is not directly related to growth and repair.
