And once again, if we read the curve backwards, so going this way, the protein is binding the oxygen, but going backwards, the protein is dissociating that oxygen. And so if we go this way, we see that our hemoglobin releases that oxygen much more readily than myoglobin. And that's exactly what makes hemoglobin much better at carrying the oxygen from the lungs and releasing it at the tissues and cells of our body. And that's exactly what the function of hemoglobin is. So myoglobin is used to actually store that oxygen in the muscle cells, while hemoglobin is used to actually carry the oxygen from the lungs through the bloodstream into the tissues and cells of our body. And only when the hemoglobin isn't able to actually bring enough oxygen to our cells, only then does myoglobin begin to release that oxygen to the muscle cells of our body.
