Question

Quizplus · Accepted Answer

Genetically determined variations in proteins involved in transport, metabolism, and excretion of environmental chemicals can affect an individual's overall risk of exposure to these chemicals. For example, some individuals may have variations in specific enzymes involved in the metabolism of toxins, which can result in either increased or decreased toxicity. Additionally, variations in transport proteins can lead to differences in how quickly and efficiently chemicals are removed from the body, which can also affect an individual's risk of exposure.
