The function of Haemoglobin is to : (1) provide amino acids (2) carry oxygen (3) provide enzymes (4) help in excretion
by

1 Answer

Answer :

(2) carry oxygen Explanation: Haemoglobin is an ironcontaining protein in red blood cells. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the rest of the body (i.e. the tissues) where it releases the oxygen to burn nutrients to provide energy to power the functions of the organism, and collects the resultant carbon dioxide to bring it back to the respiratory organs to be dispensed from the organism.
