there is probably a connection between its damaging effect on the cytochrome 

 system and its carcinogenic effect. 



5.3. The Cytochrome System in Various Organisms 



5.3.1. Cytochrome c and Cytochrome Oxidase in Animal 

 Tissues. While the distribution of cytochrome c in mammalian tissues 

 has been studied thoroughly, only a few quantitative data are avail-

" According to Stotz {367^.), Potter and DuBois (2179), Fujita and collaborators 

 (f)60). 



Keiiin and Hartree (H9Jf) found no evidence for the presence of cytochrome c in 

 the kidney cortex of the pig, although a similar cytochrome (ci ?) with an absorp- 

 tion band at 551 m^ in liquid air was observed. The band of cytochrome c under 

 the same conditions was found at 547 m/i. 



<^ Huszak (l-i77) found no cytochrome c in adrenal medulla.
