I believe it is D. the genetic variations are in the phenotype of the organism. The reason why I say this is because the phenotype is the physically noticeable characteristics in an organism, this allows them to mutate differently and only the ones who are fit enough and have the best phenotypes will survive.
Answer:
The correct answer is D. The cytochromes
Explanation:
Cytochromes are proteins which contain tightly bound heme metal which easily undergoes oxidation and reduction and are responsible for accepting and donating the electron. They play an important role in the electron transport chain and helps in formation of ATP during oxidative phosphorylation.
The metal ion provides the capability to the cytochrome to gain and loss the electron. a, b, and c are the three classes of cytochrome out of which cytochrome c is the most abundant and stable.
Therefore the redox carrier of ETC that have bounded metal atom are cytochromes.
