Web20 mrt. 2024 · How is most oxygen carried in the blood? Hemoglobin transports 98% percent of our oxygen through our blood. In the pulmonary capillaries, oxygen from the alveoli dissolves in the plasma. Dissolved O2 then diffuses into red blood cells, where it can bind to hemoglobin. What part of the blood carries the most oxygen? Red blood cells WebThe majority (around 70%) is transported within the blood as bicarbonate ions. These HCO 3 - ions are produced within the erythrocytes, through a reaction catalysed by the enzyme carbonic anhydrase (CO 2 + H 2 O ⇌ H 2 CO 3 ⇌ H + + HCO 3 _ ). These HCO 3 _ ions are then exchanged for Cl _ ions and are transported in the plasma, however the H ...
