At the alveoli, the blood capillaries are exposed to high oxygen and low carbon dioxide concentration. This concentration gradient leads to the speedy reversal of chemical events releasing CO2 and picking up O2 simultaneously. This phenomenon is supported by the Bohr’s effect. The Haldane effect is more important than the Bohr’s effect in the transport of carbon dioxide because it describes how the binding of oxygen with hemoglobin (Hb) tends to displace carbon dioxide from the blood. Therefore, both the Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.
Option a is the correct answer.
