hemoglobin
Hemoglobin, sometimes spelled haemoglobin in British Commonwealth countries.
hemoglobin
Hemoglobin binds with oxygen molecules. Hemoglobin is a protein molecule.
Red blood cells carry oxygen fro the lungs to the body cells. A red blood cell is made mostly of hemoglobin. Hemoglobin is an iron-containing protein that binds chemically to oxygen molecules. Red blood cells are produced in the bone marrow and have no nuclei.
the mineral is IRON
Molecules containing carbon, hydrogen and oxygen atoms
A protein can not be an element, because every protein must contain at least four elements: carbon, hydrogen, oxygen, and nitrogen. A pure protein is a compound, but it may be mixed either homogeneously or heterogeneously with other molecules that are so chemically similar that they are difficult to separate.
superoxide dismutase and catalase
Hemoglobin is the iron containing protein in our red blood cells that combines with and carries oxygen.
They chemically bond together t form molecules of H2O.
