Hemoglobin is a large protein molecule that is responsible for carrying oxygen through the blood. iron ions are a relatively small component of hemoglobin. there are four fe2+ions that are part of the much larger hemoglobin structure. in a single red blood cell there are 2.50x108molecules of hemoglobin. if a single fe2+ion has an atomic radius of 75.1 pm and a redblood cell has a volume of 95 μm3, what percentage of the total red blood cell volume is taken up by fe2+ions?
