Carbon Monoxide and Cyanide Poisoning in the Burned Pregnant Patient: An Indication for Hyperbaric Oxygen Therapy. These protons (eg: the same effect of a lower pH) pump back into the mitochondrial matrix through ATP synthase via the gradient. Cyanide enters water, soil, or air as a result of both natural processes and industrial activities. Cyanide gas is less dense than air, so it will rise. This causes the proton gradient to break down, stopping ATP syntesis b) Cyanide uncouples the proton gradient from the process of ATP synthesis 3 How does cyanide affect ATP production? 4 A person exposed to cyanide may have cherry-red skin from high oxygen levels or dark or blue coloring, from Prussian blue (iron-binding to the cyanide ion). Chlorination of water contaminated with cyanide produces the compound cyanogen chloride. Complex III (and, it seems, Complex IV) contains an Iron-Sulphur protein (also known as "Rieske"-protein), in which the iron-atom "oscillates" between the Ferric and the Ferrous states, facilitating temporary acceptance of the electron(s).
