Answer Bank
Carbon monoxide binds at an allosteric site, lowering oxygen binding affinity.
Oxygen binds irreversibly to this molecule.
The binding pattern for this molecule is considered cooperative.
This molecule has a greater affinity for oxygen.
The oxygen dissociation curve is hyperbolic in shape.
As oxygen binds to this molecule the shape of the molecule changes, enhancing further oxygen binding.
This molecule delivers oxygen more efficiently to tissues.
The oxygen dissociation curve is sigmoidal in shape ("S"-shaped).
