If the [Fe_4 S_4]^2+ in a metalloprotein formally containing 2 iron(II) atoms and 2 iron(III) atoms, what ate would it be found after this protein is involved in a one electron transfer process to oxidize a substrate? [Fe_4 S_4]^3 formally containing 1 iron(II) atom and 3 iron(III) atoms. [Fe_4 S_4]^3 formally containing 2 iron(II) atoms and 2 iron(III) atoms. [Fe_4 S_4]^3 formally containing 3 iron(II) atoms and 1 iron(III) atom [Fe_4 S_4] formally containing 3 iron(II) atoms and 1 iron(III) atom [Fe_4 S_4] formally containing 1 iron(II) atom and 3 iron(III) atoms
