The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins
