Answer:
given,
a typical RBC contains about 270 million hemoglobin molecules.
one Hb molecule carries 4 oxygen molecules.
1 Hb molecule contains = 4 O₂ molecules.
then, 270 million Hb will contain = 270×4 million O₂ molecules.
= 1080 million O₂ molecules.
theoretically, it is possible.
Explanation:
hemoglobin has two alpha and two beta subunits. each subunits contains 1 molecule of oxygen. 98.5% O₂ is bond to hemoglobin.
