When the electron moves back to lower energy levels in an electron transport chain, energy is a) stored or b) released c)converted to matter d)used to make O2
I'm not sure how to answer this cause isn't it stored as potential energy of H20 and just before the electron moves back the energy is released. So when it moves back would it be considered stored?

    No, if an electron goes to a lower energy level, energy is released.
