Question on: JAMB Biology - 2024
The pigment carrying oxygen in the blood is
A
plasma
B
haemoglobin
C
oxyhaemoglobin
D
erythrocytes
Ask EduPadi AI for a detailed answer
Correct Option: B
- Haemoglobin is the protein molecule in red blood cells (erythrocytes) that is responsible for carrying oxygen.* Plasma is the liquid portion of blood and does not directly carry oxygen.* Oxyhaemoglobin is the form of haemoglobin when it is bound to oxygen. Although it carries oxygen, haemoglobin itself is the pigment.* Erythrocytes are red blood cells, which contain haemoglobin, but they are not the pigment itself.
