Which aspect of genetic makeup is most likely to alter a person's response to medication?.
Distribution.
Absorption.
Excretion.
Metabolism.
The Correct Answer is D
Choice A rationale:
While distribution can affect a person’s response to medication, it is not the aspect of genetic makeup most likely to alter this response.
Choice B rationale:
Absorption can affect how a drug is taken up by the body, but it is not the aspect of genetic makeup most likely to alter a person’s response to medication.
Choice C rationale:
Excretion, or how the body eliminates a drug, can affect drug response, but it is not the aspect of genetic makeup most likely to alter this response.
Choice D rationale:
Metabolism, or how the body processes a drug, is the aspect of genetic makeup most likely to alter a person’s response to medication. Genetic differences can lead to variations in drug-metabolizing enzymes, affecting how quickly or slowly drugs are metabolized.
