WebbE cell = oxidation potential + reduction potential. Since the tabulated standard electrode potentials are reduction potentials, the one which is most negative will need to be reversed in sign to get its oxidation potential. When that is done, it is clear that the theoretical standard cell potential for the zinc-copper cell is 1.10 volts. Webb12 aug. 2024 · Early in embryonic development, it is common for cells to switch from dividing asymmetrically (into daughter cells with different sizes and developmental fates) to dividing symmetrically (into identical cells with the same fate). The size of the cells seems to be what determines when that switch occurs. BakaArts for Quanta Magazine.
