Cytochromes definition of Cytochromes by Medical dictionary

WebAs electrons move through complex III, more H ^+ + ions are pumped across the membrane, and the electrons are ultimately delivered to another mobile carrier called cytochrome C ( cyt C ). Cyt C carries the electrons to complex IV, where a final batch of H ^+ + ions is pumped across the membrane. Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding.
