What protein combines with oxygen in the blood for transport?
The protein haemoglobin found in red blood cells binds reversibly with oxygen. It is the oxygen transporter in blood, and when combined with oxygen the product is oxyhaemoglobin. One haemoglobin molecule binds with four oxygen molecules in accordance with the chemical equation:
Hb + 4O2 -> Hb(O2)4
Note: Hb is haemoglobin; Hb(O2)4 is oxyhaemoglobin
