In addition to this, amigdalin decomposes into compounds that are not important, including benzoaldehyde and glucose. Cyanide ions block the action of cytochrome oxidase in the respiratory chain, or simply cause cell death by asphyxiation.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4">[2]</a></sup> So, in order for the ions to work, the cell must use cytochromes for its respiration and hence must use the respiratory chain. In most healthy cells, this is the case, as cellular respiration consists of three steps: glycolysis, the Krebs cycle,<sup id="cite_ref-5" class="reference"><a href="#cite_note-5">[note 3]</a></sup> and the respiratory chain.
