Cyanide has a high efficiency for a protein called cytochrome oxidase. This protein exists in the membrane of mitochondria, binds to oxygen molecules, and helps the successful completion of oxidative phophorylation. It is through this process of oxidative phosphorylation that energy molecules, ATP or adenosine triphosphate, are generated.

Now, in the presence of cyanide, oxygen can not bind to the cytochrome oxidase, since these proteins bind the cyanide. This leads to the absence of electron acceptors (oxygen) from oxidative phosphorylation. This causes the inability to generate energy.

Thus, among the given options, choice "d: energy" is correct, since a mitochondria affected by cyanide will not be able to generate energy. 

All the other available options (a: lipid, b: sugar, and c: mineral) are incorrect.
