Cyanide primarily affects the electron transport chain stage of cellular respiration by inhibiting cytochrome c oxidase. Hydrogen sulfide inhibits multiple stages of cellular respiration, including the electron transport chain and specific enzymes in the citric acid cycle. Both compounds disrupt the production of ATP, leading to cellular dysfunction and potentially cell death.

Is hydrogen cyanide poisonous?
Yes, hydrogen cyanide is highly toxic. It interferes with the body's ability to use oxygen, leading to cellular suffocation. It can be lethal even in small doses.
Does cyanide block aerobic metabolism by interfering with cell use of oxygen.?
Yes, cyanide blocks aerobic metabolism by binding to cytochrome oxidase in the mitochondria, preventing the cells from using oxygen for energy production. This results in the inhibition of the electron transport chain and the production of ATP, leading to cell death.
What is the nomenclature for HCN?
The nomenclature for HCN is hydrogen cyanide.
If a cell is exposed to cyanide most of the cyanide will be found within?
If a cell is exposed to cyanide, most of the cyanide will be found within the mitochondria. Cyanide inhibits cytochrome c oxidase, a key enzyme in the electron transport chain located in the inner mitochondrial membrane, disrupting cellular respiration and leading to cell death.
How does cyanide affect diffusion?
Cyanide is a potent inhibitor of cytochrome c oxidase, an enzyme essential for cellular respiration. By disrupting this process, cyanide impairs the production of ATP, the cell's primary energy source. As a result, diffusion processes within the cell, including the movement of molecules across membranes, are disrupted, leading to cellular damage and eventually cell death.
Which cellular organelle would be affected by cyanide poisoning?
Mitochondria are the cellular organelles that would be affected by cyanide poisoning. Cyanide inhibits the enzyme cytochrome c oxidase, which is involved in the electron transport chain in the mitochondria. As a result, cells are unable to produce ATP, leading to cellular dysfunction and eventual cell death.
Which oxygenated tissues are affected by cyanide?
Cyanide primarily affects tissues with high oxygen demands such as the brain and heart. It inhibits cellular respiration by blocking cytochrome c oxidase in the electron transport chain, leading to cellular hypoxia and eventually cell death.
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.
Are cyanide and Carbon monoxide nerve agents?
No. Carbon monoxide interferes with the ability of your blood to carry oxygen while cyanide interferes with cellular respiration.
Is hydrogen cyanide poisonous?
Yes, hydrogen cyanide is highly toxic. It interferes with the body's ability to use oxygen, leading to cellular suffocation. It can be lethal even in small doses.
Does cyanide block aerobic metabolism by interfering with cell use of oxygen.?
Yes, cyanide blocks aerobic metabolism by binding to cytochrome oxidase in the mitochondria, preventing the cells from using oxygen for energy production. This results in the inhibition of the electron transport chain and the production of ATP, leading to cell death.
Which oxygen dependent tissues are severely affected by acute cyanide poisoning?
The tissues most severely affected by acute cyanide poisoning are the brain and the heart. This is because both organs have high oxygen demands and rely heavily on aerobic metabolism. Cyanide inhibits the enzyme cytochrome c oxidase in the electron transport chain, disrupting cellular respiration and leading to rapid cell death in these tissues.
What is the common name for HCN?
Hydrogen cyanide is commonly known as prussic acid.
What is the nomenclature for HCN?
The nomenclature for HCN is hydrogen cyanide.
If a cell is exposed to cyanide most of the cyanide will be found within?
If a cell is exposed to cyanide, most of the cyanide will be found within the mitochondria. Cyanide inhibits cytochrome c oxidase, a key enzyme in the electron transport chain located in the inner mitochondrial membrane, disrupting cellular respiration and leading to cell death.
Why is it not possible to survive cyanide poisoning by using anaerobic respiration alone?
Anaerobic respiration still requires oxygen to create a limited amount of energy. Cyanide prevents cells from using oxygen to create this energy, rendering both aerobic and anaerobic respiration ineffective. Without oxygen being used in cellular respiration, cells cannot produce enough energy to survive.
What chemical agent has smell of bitter almonds?
Cyanide smells of almonds.
