Explanation:
Yes, honestly there is no 100% percent accurate answer to this statement however I theorize since black holes absorb light, there should not be any reason for it to reflect light
Answer:
Electron transport chain.
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.
