12. What is Cytochrome-C? Why is it important to an organism? Why it is important to the study of evolution

Cytochromes are iron containing hemeproteins central to

which are heme groups that are primarily responsible for the

generation of ATP via electron transport. They are found

either as monomeric proteins (e. g., cytochrome c) or as

subunits of larger enzymatic complexes that catalyze redox

reactions.
