What is the shape of curve for myoglobin oxygen-binding?

The oxygen-binding curve for myoglobin is hyperbolic in shape. This reflects its function as an oxygen storage protein, where it binds to oxygen tightly in low concentrations and releases it less readily than hemoglobin. The hyperbolic curve indicates that myoglobin has a high affinity for oxygen, allowing it to effectively store oxygen in muscle tissues. Unlike hemoglobin, which exhibits a sigmoidal curve due to cooperative binding, myoglobin's binding does not involve cooperative interactions.
