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. So that means myoglobin has a very high affinity to oxygen, much more than Hemoglobin does. And it only unloads that oxygen when the partial pressure when the oxygen level inside arrivation drops to an extremely low quantity below 2 mercury. So this is the major difference between myoglobin and hemoglobin and their functionality.
