WebEnzymes are required as organic catalysts for specific reactions within the lamellae. Protein coenzymes, also called cofactors, include important electron carrier molecules called cytochromes, which are iron-containing pigments with the pigment portions attached to protein molecules. WebCytochromes are a family of related proteins that have heme prosthetic groups containing iron ions. In complex III, electrons are passed from one cytochrome to an iron-sulfur protein to a second cytochrome, then finally transferred out of the complex to a mobile electron carrier (cytochrome C).
