Web30ul of Reduced cytochrome c had an absorbance of 0.702 at 550 nm = 0.0332M (before adding mitochondria) and an absorbance of 0.135 at 550 nm =0.0063M (following the assay). WebComplex III itself is composed of several subunits, one of which is a b-type cytochrome while another one is a c-type cytochrome. Both domains are involved in electron transfer within the complex. Complex IV contains a cytochrome a/a3-domain that transfers electrons and catalyzes the reaction of oxygen to water.
