Cyanide is poisonous to cells in our body because it :
Ans: Option d The two of the above are TRUE.
Explanation:
Cyanide poisoning is a type of histotoxic hypoxia because the
cells of an organism are unable to create ATP.
It prevents the cells of the body from using oxygen which all cells
need to survive.

Inhibitors of Oxidative Phosphorylation The following chemicals inhibit oxidative phosphorylation: Cyanide: Cyanide is a naturally occurring compound that binds to protein complex IV of the mitochondrial electron transport chain and prevents transfer of electrons from the protein. Metformin: At the cellular level, chemically synthesized metformin, a drug commonly prescribed for Type 2 diabetes, inhibits mitochondrial respiration by blocking complex I. Dinitrophenol: Dinitrophenol is a metabolic poison that can be sold legally as a pesticide. Although it is lethal to humans,...

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...

Q13 Cyanide is a deadly poison that attaches to cytochrome c oxidase, the last protein in the electron transport chain before the terminal electron acceptor. Based on your knowledge of the electron transport chain, which statement below best describes the action of cyanide on the body? A. Cyanide does not allow the Krebs cycle to be completed by blocking acetyl CoA from entering this cycle. This action shuts down the entire process of cellular metabolism. B. Cyanide does not allow...

9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2. I need you to remember how "Q" moves from protein I to protein Do you remember? Don't overthink it, Preeda. As far as scientists know right now, the...
