Carbon dioxide transport in African lungfish Protopterus aethiopicus blood conformed to the typical vertebrate scheme, implying a crucial and rate‐limiting role of erythrocyte Cl–/HCO3– exchange. The rate coefficient for unidirectional Cl– efflux via the anion exchanger (k, s−1) increased with tempe...
