In this video, we’ll explore Enzyme Inhibitors, focusing on the differences between Reversible and Irreversible Inhibitors and their impact on enzyme function. Reversible Inhibitors: These inhibitors bind to enzymes temporarily, allowing normal enzyme function to resume once the inhibitor is removed. Reversible inhibitors include competitive inhibitors, which bind directly to the active site, competing with the substrate and preventing the formation of the enzyme-substrate complex. Non-competitive inhibitors, on the other hand, bind to a different part of the enzyme, altering its shape and function without directly blocking the active site. Antibiotics often act as reversible inhibitors to slow down bacterial enzymes. Examples of non-competitive inhibitors include nerve gases, cyanide, and certain heavy metals, which bind tightly to enzymes and disrupt critical biochemical pathways. In some cases, these inhibitors disrupt the disulphide bonds within the enzyme, causing irreversible ch
