How do you deactivate cytochromes?

The term 'cytochrome' means (biochemistry) a class of hemoprotein whose principal biological function is electron transfer (especially in cellular respiration)

I think if I remember well is a group of proteins or enzymes that belong to the superfamily of HEME. The metal involved has to be Fe, due to its magnetic powers to exchange protons in molecules...

nom nom nom it until it goes away

they are part of the electron transport chain and they are involved with the pumps that create the concentration gradient of H+

The cytochromes are proteins with characteristic strong absorption of visible light, due to their iron containing heme prosthetic groups. Their main function is transfer of electron in photosynthesis...
