<u>Answer:</u>
<em>The biological macro molecule protein can serve as a precursor to the production of cyanide.
</em>
<u>Explanation:</u>
<em>Cyanides are chemical compounds that contain the cyanide group(C≡N). </em>Based on the elements attached to the cyanide group cyanides can be classified into organic and inorganic cyanides.
<em>In inorganic cyanides the cyanide group is present as
ion which makes them toxic. In organic cyanides
group is not present and thus they are less toxic. </em>
Since nitrogen is the essential component in a cyanide, a biomolecule containing nitrogen will best act as the precursor to cyanide formation.
<em>The biomolecule protein is a long chain polymer of amino acids that contain nitrogen group. Thus proteins can act as precursor to cyanide formation.
