Which outcome occurs when paramagnetic oxygen binds hemoglobin's iron?

A)Changes in protein quaternary structure
B)Unstable covalent bonds degrade porphyrin
C)Increased heme iron reduction to Fe+
D)Free radical formation from singlet oxygen

💡 Explanation

Oxygen binding to hemoglobin triggers cooperative binding through conformational changes caused by *orbital interactions*. The changes allow easier subsequent oxygen binding, therefore maximizing hemoglobin's oxygen carrying capacity rather than causing heme degradation.
