This colorimetric assay is based on an observation of the decrease in absorbance at 550 nm of ferrocytochrome c caused by its oxidation to ferricytochrome c by cytochrome c oxidase.
There are three kinds of reductases that reduce trivalent iron of methemoglobin, NADH is the coenzyme of the first one, NADPH--the second one, and the third one acts with participation of ferrocytochrome [b.

Andrew McCammon and his colleagues at the University of Houston and Peter Wolynes at the University of Illinois in Urbana-Champaign simulated the molecular motions of atomic groups in the molecule ferrocytochrome C using quantum dynamic principles and found "significant differences" in how the stretching of chemical bonds and the oscillation of chemical groups was modeled.
