1. Hemoglobin is responsible for the transport of oxygen (O2) in the blood, which is indicated by the symbol O₂ in the question. Hemoglobin does not bind seven oxygen molecules; it can bind up to four oxygen molecules. Hemoglobin is made up of four polypeptide chains, not two myoglobin-like units, making statement 3 incorrect.
