D)all three stages

Question

Quizplus · Accepted Answer

Iron and copper are both necessary for the cytochrome (electron) transport system to function properly. They are involved in the final steps of aerobic respiration, where they act as electron carriers in the electron transport chain. Neither mineral is directly involved in glycolysis or the Krebs cycle.
