Cytochromes in the electron transport chain

WebCytochrome C carries the electrons to the final protein complex, protein complex 4. Once again, energy released via electron shuttling allows for another proton to be pumped into the intermembrane space. The electrons are then drawn to oxygen, which is the final electron acceptor. WebCytochromes are proteins that contain a heme prosthetic group. The heme is capable of carrying a single electron. Iron-Sulfur proteins contain a nonheme iron-sulfur cluster that …

Cytochromes are a protein complex that acts as an electron carrier in electron transport chain. Therefore, they are loosely associated with the inner membrane of the mitochondria. Moreover, they are small heme proteins.

WebCytochrome c transfers its electrons to the final electron transport component, Complex IV, or cytochrome oxidase. Cytochrome oxidase transfers electrons through a copper‐containing protein, cytochrome a, and cytochrome a 3, and finally to molecular oxygen.
