During oxygen transport by hemerythrin, oxygen is bound as
(a)$\mathrm{O_2^{-}}$ to one Fe(III) only
(b)$\mathrm{HO_2^{-}}$ to one Fe(III) only
(c)$\mathrm{O_2^{2-}}$ to one Fe(II) and one Fe(III)
(d)$\mathrm{O_2^{2-}}$ to two Fe(II)
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
In oxyhemerythrin O₂ is bound as hydroperoxide HO₂⁻ to one Fe(III) of the Fe(III)–O–Fe(III) core (b).
