Question
If a mouse carries a mutation that causes the enzyme carbonic anhydrase to be less effective, it would be reasonable to predict that the mouse would differ from a wild-type mouse in being
less effective at loading CO2 from its cells to its blood and off-loading it in the alveoli in the lungs.
more effective at loading CO2 from its cells to its blood, but less effective at off-loading CO2 from the blood to the alveoli in the lungs.
less effective at loading CO2 from its cells to its blood, but just as effective at off-loading CO2 from the blood to the alveoli in the lungs.
more effective at off-loading CO2 from the blood to the alveoli in the lungs, but less effective at loading CO2 from its cells to its blood.
less effective at off-loading CO2 from the blood to the alveoli in the lungs, but just as effective at loading CO2 from its cells to its blood.

Explanation / Answer
The enzyme carbonic anhydrase is responsible for both the pickup of CO2 from tissues and the dropoff at alveoli. Hence, less effective at loading CO2 from its cells to its blood and off-loading it in the alveoli in the lungs.
