So 66% of our hemoglobin will fully unload the oxygen to the tissues of our body, but only 7% of the myoglobin, this difference here will unload that oxygen to our tissues. So this information tells us that myoglobin binds oxygen much more tightly than our hemoglobin does. And this means that myoglobin would not make a very good oxygen carrier inside our blood because it will not be able to effectively and quickly unload our oxygen to the exercising tissues of our body that require that oxygen. Now, on the other hand, myoglobin, because it has a very high affinity to oxygen. It is a very good protein because it is a very good protein store, which basically means it can actually store our oxygen inside the muscle tissue until our partial pressure drops to very low value. In fact, we see from this graph that when the partial pressure of oxygen inside the muscle tissue drops to about 2 mercury, which is a very small value, the myoglobin will only unload about 50% of that oxygen.
