It acts as an irreversible enzyme inhibitor, preventing cytochrome C oxidase from doing its job, which is to transport electrons to oxygen in the electron transport chain of aerobic cellular respiration. It does so by binding to the enzyme cytochrome Coxidase and blocks the mitochondrial transport chain. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. This effectively halts cellular respiration by blocking the reduction of oxygen to water. 5 How does cyanide affect aerobic respiration? How cyanide affects the electron transport chain. Cyanide inhibits cellular oxygen metabolism and energy production, killing a severely exposed individual in minutes. The health department or emergency personnel will arrange for further disposal. This blocks the transfer of electrons from the cytochrome c molecule to the oxygen in the air molecule, leading to the production of energy in the form of heat. Centers for Disease Control and Prevention, 2018. Rotenone also affects oxidative phosphorylation, by inhibiting electron transfer from cytochrome 1 to ubiquinone, making it a potent insecticide. Since no ATP is made, the electron transport chain stops working. Cyanide can be a colorless gas, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl), or a crystal form such as sodium cyanide (NaCN) or potassium cyanide (KCN). Concomitant with this process of oxidative phosphorylation, between 30% and 80% of the CO 2 fixed over the lifetime of a plant through photosynthesis is released into the atmosphere through . Despite its toxicity, cyanide has many roles in industry and medicine. Any clothing that has to be pulled over the head should be cut off the body instead of pulled over the head. 6.
