The electron transport chain can stop because it does not have a source of electrons, or it can stop because it can no longer pass electrons on. The first scenario would be caused by something like starvation. Without a source of glucose or other energy-rich molecules, cells would not be able to collect electrons on electron carriers. Without anything to transfer, the chain would simply stop. There is huge potential to produce Magnesium ore Eco-cements, Magnesium cements absorb CO2 as they set, Magnesium cements can have greater compressive and tensile strength, greater capacity to breathe and to bond.
