Does cyanide inhibit ATP synthase? – KnowledgeBurrow.com

WebWhen phosphorylation is partially uncoupled from electron flow, one would expect a decrease in the proton gradient across the inner mitochondrial membrane and, hence, impaired ATP synthesis. In an attempt to compensate for this delect in energy capture, metabolism and electron flow to oxygen is increased. WebCyanide is an extremely effective reversible inhibitor of cytochrome oxidase. A concentration of 1 mM KCN is sufficient to inhibit oxygen consumption by mitochondria from a vertebrate source by >98%. For a nominally 2 ml chamber, a convenient concentration for the stock solution would be 0.5M (20 µl produces a 2.5 mM final concentration).
