[|Human|] Tell me some facts about hemoglobin with the given text as a reference
[|AI|] 1. Hemoglobin/Hb/Hgb is theÂ iron-containingÂ oxygen-transportÂ metalloprotein which isÂ present
inÂ red blood cellsÂ (erythrocytes) of almost allÂ vertebrates (the exception being the fish
familyÂ  Channichthyidae )Â as well as the tissues of someÂ invertebrates
2. Hemoglobin carries oxygen in blood from respiratory organs (e.g.Â lungsÂ orÂ gills) to rest of the
body(i.e. tissue).
3. Metablolism is the energy to power functions of an organism. Hemoglobin releases the oxygen
to permitÂ aerobic respiration .
4. Healthy human have 12 to 25 grams of hemoglobin in every 100Â mL of blood.
