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!
Cyanide binds to cytochrome c oxidase (last enzyme in the respiratory electron transport chain of mitochondria). It prevents electron transport to oxygen in the chain. This disrupts aerobic ATP production.
The effect of cyanide on active transport is the reduction resistance of the cell membranes. There is also an increase of the potassium selectivity of cell membranes.
The cyanide ion halts cellular respiration by inhibiting an enzyme in the mitochondria called cytochrome c oxidase. (Wikipedia)
Of course it does. It interfere Oxygen binding

ATP decreases
Cyanide binds with at least one molecule involved in producing ATP. If a cell is exposed to cyanide, most of the cyanide would be found within the mitochondria?
The mitochrondria main function is to produce ATP. ATP is the currency of cells, with out this currency cell function slows down, then eventually can cease. Therefore, any disorder that leads to substantial reduction in ATP production cause lethal problem in the CNS, which needs a continuous supply of ATP. Cyanide poison works this way. it inhibit the electron transport system in the mitichondria, thus resulting death.
Potassium cyanide
It blocks the final electron receptor, oxygen. So the cells do not complete the production of ATP and die.
ATP decreases
Cyanide acts at the level of the cell mitochondria (the cell's energy factory) to stop the utilization of oxygen in the formation of energy (adenotriphosphates - ATP). Without this energy (ATP), cells cannot function and ultimately die. Cyanide has the same effect in humans... you can die of cyanide poisoning.

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.
Cyanide blocks cytochrome c oxidase in the mitochondria. This is a transmembrane protein that establishes a proton gradient used by ATP synthase to create ATP. This shuts down ATP production leading to a quick death if exposure is high enough.

Cyanide
ATP is known as Adenosine TriPhosphate. Hence the abbreviation ATP. ATP is produced by the ribosome in a cell. ATP is energy for the cell.
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.
