Cyanide acts as a mitochondrial poison by blocking the final step in the electron transport chain What will happen to human red blood cells if they are placed in an isotonic solution containing cyani?
The cells will probably be unaffected.
Why is cyanide a poison?
Cyanide is lethal because it contains an ion that binds to enzymes and decrease their activity. It causes the entire cell to stop producing ATP (energy) through an ETC (electron transport chain). This effects some important tissues, like the heart and central nervous system, that process respiration. There are some compounds like hydrogen cyanide and sodium cyanide that are very dangerous and hazardous to the human body. An example of cyanide poisoning can be related to some mass extermination camps during the time of the Holocaust.
How does cyanide and DNP work on cellular respiration?
Cyanide blocks the last step in the production of ATP. The binding of cyanide to cytochrome c oxidase prevents transport of electrons from cytochrome c to oxygen. No ATP will be produced. The central nervous system and the heart are the most to be affected. Death can occur in minutes.
What prevents active transport taking place?
Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
Does cyanide contain carbon?
Yes cyanide is CN-
To which component of the electron transport chain does cyanide bind?
Cyanide binds the electron transport chain at the level of complex IV
Oxygen is known as the "terminal electron receptor" in the electron transport chain. Suppose an organism lacks the ability to breathe in oxygen.What is the most likely effect an oxygen deficit would have on the electron transport chain in mitochondria?
Cyanide binds the electron transport chain at the level of complex IV
Why cynide is the most poisonous for animals?
Spelt cyanide....blocks electron transport in mitochondria and prevents production of ATP.
Without a terminal electron acceptor, the electrons of and would have nowhere to be released, and all of the enzyme complexes involved with the electron transport chain?
Cyanide binds the electron transport chain at the level of complex IV
What is the effect of cyanide on ATP function?
Cyanide inhibits respiration. By inhibiting respiration, you also inhibit active transport because active transport requires energy from ATP made in respiration. Remember: anything that affects respiration, affects active transport too, because it is an energy requiring process!
Since cyanide is a poison that limits a cells ability to manufacture ATP a cell containing cyanide is least likely to carry on the process of?
Cellular respiration. More specifically, electron transport chain. Cyanide doesn't just simply limit manufacturing of ATP, it blocks the enzyme cytochrome C oxidase, a crucial enzyme in the electron transport chain. Since ETC is the largest supplier of ATP, the ATP supply in the cell declines rapidly.
Which organs are affected by cyanide poisoning?
The binding of cyanide to cytochrome c oxidase prevents transport of electrons from cytochrome c to oxygen in the mitochondria.As a result, the electron transport chain is disrupted, meaning that the cell can no longer aerobically produce ATP for energy. The central nervous system and the heart, are particularly affected. Oral ingestion of a small quantity of solid cyanide or a cyanide solution as little as 200 mg, or to airborne cyanide of 270 ppm is sufficient to cause a very painful death within minutes.The binding of cyanide to cytochrome c oxidase prevents transport of electrons from cytochrome c to oxygen in the mitochondria.As a result, the electron transport chain is disrupted, meaning that the cell can no longer aerobically produce ATP for energy.

Give a reason why cyanide effects the cellular respiration process if it enter the cell?
Cyanide deactivates the enzyme cytochrome c oxidase. This is the last enzyme of the electron transport chain (the final step of cell respiration). The electron transport chain allows a great concentration of protons (H+ ions) to build up in the matrix of mitochondria so that they can diffuse back through a channel which in turn synthesises ATP. So basically cyanide stops the last step of cell respiration from occurring and as such inhibits ATP synthesis.
What process does Cyanide stops the production of ATP?
It blocks the final electron receptor, oxygen. So the cells do not complete the production of ATP and die.
A drug is introduced into cells that affects the mechanics of the electron transport chain. Specifically, this drug completely inhibits the flow of electrons through the electron transport chain and also completely halts the synthesis of ATP?
Cyanide, which inhibits the activity of cytochrome C oxidase
The cyanide ion is represented by the chemical formula what?
Cyanide is CN- , triple bonded C to N by three covalent electron pairs and each atom also has one free electron pair.

The cells will probably be unaffected.
