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.
During photosynthesis, the plant needs carbon dioxide and water-- both of which are released into the air during respiration. And during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis!
Answer:
Answer: water vapor, carbon dioxide, methane, nitrous oxide.
Explanation:
I got it right, I hope this helps. Good luck! :)
The correct answer is: When a sperm cell penetrates the oocyte membrane
The oocyte (is arrested at an early stage of the first meiotic division as a primary oocyte. During each menstrual cycle, one the day before ovulation gonadotropin hormone (luteinizing hormone) stimulates completion of meiosis 1. After the meiosis 1, 2 haploid daughter cells are formed: one becomes the secondary oocyte the other forms the first polar body. Newly formed secondary oocyte starts meiosis 2 which arrests at metaphase which will continue after the fertilization.
