WebCytochrome c is a heme protein that is localized in the compartment between the inner and outer mitochondrial membranes where it functions to transfer electrons between complex III and complex IV of the respiratory chain. From: Vitamins & Hormones, 2014 View all Topics Add to Mendeley About this page Metabolic Regulation of Apoptosis in Cancer WebJul 30, 2024 · What are Cytochromes? 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. The overall pathway for electron transport is therefore: or:
