The main role of Hb is to carry oxygen (O2) to respiring cells across the body. Haemoglobin is a quaternary structure that contains 4 polypeptide chains. |
|
What is Affinity for O2? What does Affinity depend on? |
Affinity for O2 is the tendency a molecule has to bind to O2. Affinity depends on Partial Pressure of Oxygen (pO2). |
|
When does O2 load onto Hb to form Oxyhaemoglobon? (HbO8) Formula for O2 binding to Hb? |
O2 loads to Hb to form HbO8 where there's high pO2. Hb + O2 《==》HbO8 |
