What Factor(s) Influence(s) the Binding of Oxygen to Myoglobin

Question

What factor(s) influence(s) the binding of oxygen to myoglobin? A) the concentration of bicarbonate ion, HCO3^- B) the partial pressure of oxygen, pO2 C) the concentration of hemoglobin present D) the concentration of 2,3-BPG E) both the partial pressure of oxygen, pO2and the concentration of 2,3-BPG

Accepted Answer

The binding of oxygen to myoglobin is primarily influenced by the partial pressure of oxygen (pO2). Myoglobin's affinity for oxygen is not directly affected by bicarbonate ion concentration, hemoglobin concentration, or 2,3-BPG concentration, making the partial pressure of oxygen the correct answer.
