==Tipos==
Hai varios tipos de citocromos que se poden distinguir por [[espectroscopía]], estrutura exacta do seu grupo hemo, sensibilidade aos inhibidores, e potencial de redución.
Several kinds of cytochrome exist and can be distinguished by [[spectroscopy]], exact structure of the heme group, inhibitor sensitivity, and reduction potential.
Podemos distinguir tres tipos de citocromos polos seus [`grupo prostético|grupos prostéticos]]:
Three types of cytochrome are distinguished by their prosthetic groups:
