Cytochromes definition

WebSep 5, 2024 · A cytochrome is a protein involved in electron transfer that contains a heme group. The heme groups alternate between ferrous (Fe2+) and ferric (Fe3+) states during the electron transfer. 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.
