Substrate inhibition kinetics in drug metabolism reactions

WebAt low concentrations of substrate, the inhibitor competes for the enzyme effectively, but at high concentrations of substrate, the inhibitor will have a much reduced effect, since the substrate outcompetes it, due to its higher concentration (remember that the inhibitor is at fixed concentration). Webinhibitor is binding to the same site as the substrate. So, as is the case with high KM, it is necessary to have more substrate to achieve a higher reaction rate, since the substrate can outcompete for the binding sites. 2.
