Out of total oxygen transported,the plasma carries . . . . . . in dissolved state.

Every $100 \ ml$ of deoxygenated blood delivers approximately $.......$ of $CO_2$ to the alveoli $:$ (in $ml$)

Carbonic anhydrase is found in

$A$ major percentage $(97 \%)$ of $O_{2}$ is transported by RBCs in the blood. How is the remaining percentage $(3 \%)$ of $O_{2}$ transported?

Which factors in the tissues favor the dissociation of oxygen from oxyhaemoglobin?

Which enzyme is present in $RBC$s and plasma to catalyse the given reaction: $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^+ + HCO_3^-$?
