Solved Hemoglobin is a protein that carries oxygen in the
Hemoglobin is a protein that carries oxygen in the blood and can be represented as Hb. In your lungs, hemoglobin (Hb) reacts with four oxygen molecules (40.) to form HWO), The blood carries this molecule to your muscles, where Hb (Q), releases the oxygen, leading to the products Hb and four oxygen molecules.
