Cyanide binds to a molecule involved in the production of atp. if a cell is exposed to cyanide, you can expect most of the cyanide to be found in the:

The cyanide wound be found in the Mitochondria.

Explanation:

Cyanides are toxic substances that affect the cells of the body by reducing oxygen and it is harmful to brain and heart because the two organs requires oxygen. Cyanide's attach to the Mitochondria of the membrane cells. Cyanide's inhibit Mitochondrial enzyme cytochrome c oxidase. The enzymes is the terminal complex of electron transport chain. Cyanides bind to the iron atom of cytochrome c oxidase, preventing the release of hydrogen ion in the intermembrane space which activitate ATP synthase to produce ATP needed for cells. In the absence of ATP, the cells dies.
