    Macromolecules: TEAS Practice Question with Answer & Explanation

    An original TEAS 7-style science practice question, written for nursing-school applicants — with a full breakdown of every answer choice.

    Question

    Which class of biological molecule includes enzymes?

    • A.Carbohydrates
    • B.Lipids
    • C.Proteins
      Correct
    • D.Nucleic acids

    Correct answer: C. Most enzymes are proteins whose three-dimensional shapes allow them to catalyze reactions.

    Why C is correct

    Most enzymes are proteins whose three-dimensional shapes allow them to catalyze reactions.

    TEAS skill review

    This question tests macromolecules, a concept that can appear in the TEAS science section. Read the prompt carefully, identify the rule or evidence being tested, and eliminate options that do not directly satisfy it.

    Why the other choices are incorrect

    The remaining choices conflict with the relevant fact, calculation, language convention, or passage evidence. Check every option against the exact wording of the question rather than choosing an answer that is only generally related to the topic.

    Quick study tip: Associate enzymes with protein structure and catalysis.
