Cytochromes carry electrons
WebCoenzyme Q passes electrons through iron–sulfur complexes to cytochromes b and c 1, which transfer the electrons to cytochrome c. In the ferric (Fe 3+) state, the heme iron can accept one electron and be reduced to the ferrous state (Fe 2+). Since the cytochromes carry one electron at a time, two molecules on each cytochrome complex are ... WebWithin proteins, electrons are transferred between flavin cofactors, iron–sulfur clusters and cytochromes. There are several types of iron–sulfur cluster. The simplest kind found in the electron transfer chain …
