Determine which statements apply to hemoglobin, myoglobin, or neither. Hemoglobin Myoglobin Neither Answer Bank This molecule has a greater affinity for oxygen. Oxygen binds irreversibly to this molecule. The binding pattern for this molecule is considered cooperative. As oxygen binds to this molecule the shape of the molecule changes, enhancing further oxygen binding. The oxygen dissociation curve is hyperbolic in shape. This molecule delivers oxygen more efficiently to tissues. The oxygen dissociation curve is sigmoidal in shape ("S"-shaped). Carbon monoxide binds at an allosteric site, lowering oxygen binding affinity.
