It is a tetrameric protein and contains the heme prosthetic group attached to each subunit. It is a respiratory pigment and helps in transporting oxygen as oxyhaemoglobin from the lungs to different parts of the body.

"WebRed blood cells are considered cells, but they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria. Red blood cells cannot divide or replicate like other bodily cells. They cannot independently synthesize proteins. The blood's red color is due to the spectral properties of the hemic iron ions in hemoglobin. " - Hemoglobin is synthesized in the nucleus

Hb is highly ... WebRBCs are produced with nucleus in bone marrow, it is during their maturation that they lose nucleus. In absence of nucleus they are not able to replicate, and also since they cannot transcribe mRNA, they can't produce protein, so hemoglobin which is essentially a protein is produced during precursor stage of RBC development.

WebHemoglobin is composed of four protein subunits, two alpha chains and two beta chains, and a heme group that has iron associated with it. The iron reversibly associates with oxygen, and in so doing is oxidized from Fe 2+ to Fe 3+. In most mollusks and some arthropods, (b) hemocyanin delivers oxygen.

Ribosomes are structures found in the cytoplasm of cells that build proteins. The information needed to build hemoglobin is stored in the form of a gene (DNA). DNA is found in the nucleus of eukaryotic cells. So how can ribosomes which aren't in the nucleus use the information stored in the nucleus to build a protein?

WebHemoglobin is a large molecule made up of proteins and iron. It consists of four folded chains of a protein called globin, designated alpha 1 and 2, and beta 1 and 2 (Figure 3a). Each of these globin molecules is bound to a red pigment molecule called heme, which contains an ion of iron (Fe 2+) (Figure 3b). Figure 3.
