What Role Does the Concentration Gradient Play in Toxicokinetics?
Toxicokinetics involves the study of how a chemical substance enters the body and its subsequent distribution, metabolism, and excretion. The concentration gradient is integral to these processes. For instance, once a toxicant enters the bloodstream, its distribution to various tissues is influenced by concentration gradients across cell membranes. Similarly, the elimination of toxicants through organs like the liver and kidneys is also driven by concentration gradients.
