#### Explanation:

**More efficient buffering system**

Let's write the equations as

and

The more efficient buffering system will be the one with

Both systems are good buffers, but the

**Ratio of protonated to unprotonated forms**

The ratio of the protonated to the unprotonated form of haemoglobin is 4.2:1.
