The Bohr effect is not strictly related to CO 2 transport but is the reverse of the Haldane effect. The Bohr effect refers to the reduction in affinity of haemoglobin for oxygen in the presence of a reduction in pH or an increase in CO 2.This phenomenon allows offloading of oxygen at the tissues where the pH is lower as CO 2 is produced there. 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. chucks all star website
