WebABSTRACT. In 1904 Bohr, Hasselbalch and Krogh showed that carbon dioxide diminished the affinity of haemoglobin for oxygen. This phenomenon, known as the “Bohr effect,” together with the reciprocal effect of oxygenation upon the combination of carbon … WebOct 14, 2013 · Oxygen transport • Haemoglobin is made up of four subunits (2 alpha, 2 beta haem groups) and an iron atom. There are many specialised respiratory pigments that are able to reversibly bind to a respiratory gas. • 4Hb + 4O2 ↔ Hb4O8 • When an oxygen molecule binds to one subunit , it increases the affinity of the other subunits.
