Haemoglobins Flashcards
Structure of haemoglobins
Quaternary structured proteins made of two alpha and two beta polypeptides chains.With a heam prosthetic group containing heam and iron, that combines well with oxygen. As iron is known to attract oxygen
What is the colour of heamoglobins that has no oxygen
Bluey-red colour
what is the name of haemoglobin that has no oxygen saturation
deoxyhaemoglobin
What is the affinity of haemoglobin for oxygen?
The ability of haemoglobin to attract or bind with oxygen
What does the saturation of haemoglobin with oxygen mean?
The maximum amount of oxygen haemoglobin is holding onto
What does loading/association mean?
The binding of oxygen to haemoglobin
What does unloading/dissociation mean?
When oxygen releases, detaches, unbinds from haemoglobin
Where is haemoglobin found ?
Its a protein found in the red blood cells
What is the role of haemoglobins?
The role of haemoglobin in the red blood cells is mainly the transport of oxygen,for aerobic respiration and also other gases like carbon dioxide.
