Non-Competitive Inhibitors

In this video, we explore the effect of non-competitive inhibitors on enzymes. First we explore the features of a non-competitive inhibitor and where they bind on enzymes. We then look at how non-competitive inhibitors reduce the rate of an enzyme-catalysed reaction. Finally, we see why the effect of a non-competitive inhibitor cannot be overcome by increasing the concentration of the substrate.
