Many of today's crew-cab pickups have the same legroom as a luxury sedan, and even shoppers who don't go for a crew cab will find that many extended-cab trucks have more passenger room than you'd need under usual circumstances.
n. The protein in the red blood cells of vertebrates that carries oxygen from the lungs to tissues and that consists of four polypeptide subunits, each of which is bound to an iron-containing heme molecule.[Ultimately short for. : hematin + globulin .].. The protein in the red blood cells of vertebrates that carries oxygen from the lungs to tissues and that consists of four polypeptide subunits, each of which is bound to an iron-containing heme molecule. [Ultimately short for.
A red blood cell contains hemoglobin (Hb) which is a protein that is capable of binding oxygen (O2). The protein Hb has four subunits that are all capable of binding O2 b/c they contain a heme group that has a high affinity for O2.So the maximum potential for a red blood cell is 4 oxygen molecules. red blood cell contains hemoglobin (Hb) which is a protein that is capable of binding oxygen (O2).
