Which is called Hamburger shift?

Carbonic anhydrase occurs in $-$

The amount of oxygen transported by one litre of blood under strenuous condition is approximately (in $ml$)

The toxic effect of carbon monoxide is due to its greater affinity for haemoglobin as compared to oxygen, approximately by (in $\times$)

Haemoglobin $(Hb)$ transports oxygen from the lungs to tissues. The partial pressure of oxygen in the lungs is different from that in the tissues. Each $Hb$ can bind to up to four oxygen molecules. Suppose we have an equal number of $Hb$ and oxygen molecules,and all the oxygen molecules are in a bound form. Then,which of the following is true?

Analogy type question:
$(1)$ Carbonic anhydrase : High concentration in $RBC$ :: In blood plasma : .......
