What Role Do Cell Membranes Play in Toxicokinetics?
Cell membranes are integral to toxicokinetics, which involves the absorption, distribution, metabolism, and excretion of toxins. The membrane's selective permeability dictates how toxins enter cells. For instance, small non-polar molecules can diffuse through, while larger or charged molecules may require transport proteins. This selective permeability impacts the rate and extent of toxin absorption and distribution within the body.
