Question

Difference between oxyhaemoglobin and carboxyhaemoglobin?(In Points)

Answer 1

Explanation:

Carboxyhaemoglobin refers to the haemoglobin which is combined with carbon monoxide instead of oxygen. ... Oxyhaemoglobin refers to the haemoglobin which is combined with oxygen from the lungs. Oxygen in the body is transported in the form of oxyhaemoglobin. This is the normal form of haemoglobin existing in the body.

Answer 2

Oxyhaemoglobin:

• The haemoglobin that has been bonded to oxygen is called oxyhaemoglobin, and it is this form that oxygen is delivered to tissues from the lungs.
• Reversible oxygen binding to haemoglobin results in oxygen dissociating and being released from the tissues.
• Four oxygen molecules are bonded to one haemoglobin by each.
• Oxygen binds to haemoglobin in a cooperative and reversible manner. The concentration of H+, temperature, pO2, and pCO2 are the main factors that affect oxygen binding.
• There are two of each type of the four subunits found in mature human haemoglobin.

Carboxyhaemoglobin:

• Red blood cells create carboxyhemoglobin, also known as carboxyhaemoglobin, or carboxyhaemoglobin, when exposed to carbon monoxide.
• Its symbol is COHb or HbCO.
• It's common to confuse carbaminohemoglobin, which is what results when carbon dioxide (carboxyl) and haemoglobin combine, with carboxyhemoglobin.
• The term "carbonylhemoglobin" is the preferred IUPAC nomenclature.
• It first appeared when carbon monoxide was known by its previous name, "carbonic oxide," and developed through Germanic and British English etymological influences.
