None of the other answer options is correct. For example, we could have determined that the rusting of iron is a redox process by simply noting that it involves the formation of ions (, To help identify these less obvious redox reactions, chemists have developed the concept of oxidation numbers, which provides a way to track electrons before and after a reaction. The majority of the energy captured in the citric acid cycle is in the form of: 3. reduced because it lost 3e. aerobic in some organisms but anaerobic in others. Both oxidation and reduction occur simultaneously and in equivalent amounts during any reaction involving either process. The gene that causes sickle-cell disease is present in a higher percentage of residents of sub-saharan africa than among those of african descent living in the united states. the same element, so there's no difference.
