Question

define oxygenation of haemoglobin​

Answer 1

Answer:

The hemoglobin molecule in the red blood cells (RBC) serves to transport oxygen from the lungs to the tissues and binds to four oxygen atoms to form the oxygenated hemoglobin (HBO2) molecule [1]. ... The oxygenated hemoglobin absorbs more of the infrared light and the deoxygenated hemoglobin absorbs more of the red light.

Answer 2
