Cytochromes:- They are iron containing hemoproteins that serve many cellular functions including energy production, steroid biosynthesis, and degradation of toxins.
Cytochromes occur in all organisms except a few obligate anaerobes. They are structurally similar among organisms. These are proteins to which one to two tetrapyrrole rings are bound. These tetrapyrroles are very similar to the chromophores of chlorophylls in plants. However, chlorophylls(in plants) contain Mg++ as the central atom in the tetrapyrrole, whereas the cytochromes(in aerobic animals) have an iron atom (Figure).
Answer: Protiens help provide structural support for our metabolism, and they can act as enzymes, carriers, or hormones to help us. They provide growth and maintenence and also act as messengers for our brain. They bolster our immune system and also transport/store nutrients. Basically, they do a whole lot!
