Cytochromes contain a heme group similar to that in hemoglobin. The iron atom (Fe) in the center of the group can be oxidized and reduced. If someone was suffering from iron deficiency anemia, what stage of cellular respiration would be most affected?

The Electron transport chain.

Explanation:

Cytochrome are proteins that contain iron h containing group heme that transport electrons during cellular respiration. If Heme accept electrons, it become oxidized and changes from ferric state to ferrous state. Cytochrome is composed of two enzyme complex that comprise of electron transport chain. The chain is the end of oxidative phosphorylation in which organism synthesize ATP for life processes. A person suffering from iron deficiency anaemia would be affected at electron transport chain of cellular respiration.
