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.
You don’t have any options so idk
Would it be orange, and wouldn’t this go under chemistry
No mitosis nor cellular respiration is not the same thing
You see mitosis is the division of cells and cellular respiration is using a more usable energy
So they are not the same
As you go higher it gets colder, so the temperature fro Mesosphere would be 90 C
