Draw and label the myoglobin binding curve. - Answer A hyperbolic curve -> Y is the fraction of ligand-binding sites -> Kd is the dissociation constant (x value of y = 0.5) -> A high Kd means more dissociation. -> P50 is the partial pressure when oxygen (or something) occupies 50% of the binding sites. What does the hyperbolic shape tell us about the sensitivity of myoglobin to changes in ligand concentration? - Answer Myoglobin is very sensitive to ligand and will take up a lo...
