The US is considered a terrorist regime outside the United States. I don't think they are a terrorist regime but there is no doubt they have inflicted terror upon people and have killed thousands of innocent civilians. Source(s): aliasasim Â· 9 years ago.
Hemoglobin consists of four subunits, each with a cofactor called a heme group that has an iron atom center. The iron is the main component that actually binds to oxygen, thus each hemoglobin molecule is able to carry four molecules of O 2.
A hemoglobin abnormality is a variant form of hemoglobin that is often inherited and may cause a blood disorder (hemoglobinopathy). Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body.It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the building blocks of proteins.emoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body.
