Iron
Iron is bound to the center of hemoglobin, which transports oxygen. Depending on the meaning of element in the question, it could be Iron(most likely) or hemoglobin. ADDED: It is the iron: 4 iron molecules held within the haemoglobin molecule's hydrocarbon lattice. The oxygen binds physically to the Fe without reacting chemically.
The mineral element connected to hemoglobin is Iron.
The electrolyte iron is important in the production of hemoglobin.
Iron.
Iron (Fe) is a trace element that contributes to the composition of the protein called Hemoglobin. Hemoglobin is carried in red blood cells. Hemoglobin's main job is to carry oxygen throughout the body. So, when a person does not have enough iron in their body, they will begin to feel drowsy and fatigued, because the proper amount of oxygen is not available. This condition is called Anemia.
Iron plays a critical role in the formation of hemoglobin.
Iron
Hemoglobin is a protein and it has an iron ion that can attract an oxygen molecule to it. Both proteins and iron can be found in food.
Iron. This element is found at the center of each hemoglobin molecule.
