Question

.In deoxyhemoglobin, the oxidation state of iron is​

Answer 1

Explanation:

Fe oxidation state in hemoglobin

In binding, oxygen temporarily and reversibly oxidizes (Fe2+) to (Fe3+) while oxygen temporarily turns into the superoxide ion, thus iron must exist in the +2 oxidation state to bind oxygen. If superoxide ion associated to Fe3+ is protonated, the hemoglobin iron will remain oxidized and incapable of binding oxygen.
