Students have asked these similar questions
How many molecules of oxygen can each hemoglobin molecule transport? What part of the hemoglobin binds the oxygen?
The ability of hemoglobin to bind oxygen decreases with decreasing oxygen concentration and also decreases with increasing carbon dioxide concentration. What effect do these phenomena have on the delivery of oxygen to tissues?
What is in hemoglobin that brings oxygen to the different parts of the body?
