Question

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?

Answer 1

Answer: The Electron transport chain.

Step-by-step 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.

Answer 2

Electron transport chain.

Step-by-step explanation:

Cytochrome is a hemoprotein, the protein that contain heme as a cofactor. As mentioned in question that the iron atom can be reduced and oxidized so cytochrome can perform functions of electron transfer reactions.

The deficiency of iron would affect all processes in which cytochrome is involved. In cellular respiration the process of oxidative phosphorylation would be affected by iron deficiency.

The cytochrome C is involved in transferring the electrons from complex III to complex IV in electron transport chain. That why the stage of ETC would be most affected.
