How many molecules of o2 can a single hemoglobin molecule carry when fully saturated?

4 molecules

Explanation:

Hemoglobin, a protein with a molecular weight of about 68,000 enclosed in erythrocytes or red blood cells, makes this transport possible. Each hemoglobin molecule is capable of transporting 4 oxygen molecules, which gives rise to the mass ratio of 1: 530 which implies the analogy of the truck with which these lines began.

Few proteins have been studied as hemoglobin. And it is precisely the molecular level studies of the structure and function of hemoglobin that allow us to conclude that this waste is necessary to ensure in an exquisite way the perfect functioning of oxygen transport. From a molecular perspective, the structure of hemoglobin and that of myoglobin, another protein, present in the tissues, with a complementary function to that of hemoglobin is reviewed.
