Is cytochrome c membrane bound
WebMay 1, 2024 · Cytochrome c is a water soluble electron transport protein that is loosely associated with the mitochondrial inner membrane. WebCytochrome c, shown here from PDB entry 3cyt , is a carrier of electrons. Like many proteins that carry electrons, it contains a special prosthetic group that handles the slippery electrons. Cytochrome c contains a heme group with an iron ion gripped tightly inside, colored red here. The iron ion readily accepts and releases an electron.
