The changes that occur when O2 binds to hemerythrin are:

(A) One ion atom is oxidized.

Explanation:

Hemerythrin is a non-heme iron protein found in marine invertebrates that functions as an oxygen carrier. It contains two iron atoms that can bind to oxygen molecules. When O2 binds to hemerythrin, one of the iron atoms is oxidized from the ferrous (Fe2+) to the ferric (Fe3+) state, resulting in the formation of a peroxide bridge between the two iron atoms. This oxidation reaction is shown below:

Fe2+ + O2 → Fe3+ - O2-

The peroxide bridge stabilizes the bound O2 molecule and prevents it from dissociating from the iron atoms.

In addition to the oxidation of one iron atom, there is no hydrogen bonding involved in the binding of O2 to hemerythrin. The binding of O2 to hemerythrin is purely based on the coordination of the O2 molecule with the iron atoms.

Therefore, the correct answer is option 'A' - One ion atom is oxidized.

The changes (from A–D given below) which occur when O2 binds to ...
In hemerythrin,One Fe is hexacordinated and saturated while other Fe is pentacoordinated and unsaturated. This unsaturated Fe will be connect with the oxygen. In hemerythrin the two Fe are connect with each other by three bridge from which one is of hydroxide bridge.. Here between this hydroxide and oxygen added.. Hu bonding is occur..Here oxygen attached Fe is oxidize due to formation of peroxide by oxygen while other Fe will be oxidized due to Hu bonding of hydroxide with that peroxide. So option B and C are correct.
