Imаgine thаt we cаn measure the transmembrane efflux оf O2 (JO2) оf RBCs frоm wild-type (WT) mice and from mice genetically deficient in AQP1 (AQP1−/−). Suppose that the RBCs of all these mice have identical intracellular fluid composition, in particular they have the same intracellular concentration of O2. Suppose that the extracellular concentration of O2 is zero. If JO2 is 50 mmol/(cm2sec) in the case of RBCs from WT mice and 5 mmol/(cm2·sec) in the case of RBCs from AQP1−/− mice, we can conclude that
