Cyanide poisoning occurs when cyanide, a cellular toxin, disrupts the cell's ability to complete cellular respiration. This ultimately causes the cell to be unable to produce enough ATP for survival.

Cyanide poisoning occurs when cyanide a cellular toxin disrupts the cells ability to complete cellular respiration This ultimately causes the cell to be unable class=

Respuesta :

B.

Unable to produce ATP-> no energy-> powerhouse of cell destroyed-> mitochondrion (B)

In case of cyanide poisoning, the cell will unable to produce ATP, no energy, the cell will be destroyed . Hence option B is correct.

What Is Cyanide?

It is carbon-nitrogen (CN) molecule, some are not deadly but some are poisonous such as sodium cyanide, potassium cyanide, hydrogen cyanide etc.

The deadly cyanide when present in a cell, a cellular toxin which degrade the cell and destroy its ability to complete cellular respiration.

The harmless cyanide present in nitriles applied in the field of pharmaceuticals as they do not release the metabolic poison such as CN- ion.

Cyanide ion play as an irreversible enzyme inhibitor which prevent mode of action of cytochrome C oxidase from doing its job so that transport electrons to oxygen in the electron transport chain is inhibited and interrupt of aerobic cellular respiration.

So that mitochondria will be unable to produce the energy carrier adenosine triphosphate in absence of oxygen.
