Vedclass · Answer

(A) The Bohr effect describes how an increase in $CO_2$ concentration and a decrease in $pH$ (increase in $H^+$ ions) shift the oxygen-haemoglobin dissociation curve to the right,thereby reducing the affinity of haemoglobin for oxygen.Near the organ tissues,the partial pressure of $CO_2$ is high and the partial pressure of $O_2$ is low. This environment promotes the dissociation of oxyhaemoglobin,allowing oxygen to be released into the tissues.Since the Reason directly explains the mechanism (reduced affinity due to high $CO_2$) that causes the phenomenon described in the Assertion,the Reason is the correct explanation of the Assertion.

Assertion : Oxyhaemoglobin dissociates near the organ tissue due to Bohr effect and oxygen is released.
Reason : Increased $CO_2$ concentration reduces the affinity of haemoglobin for oxygen.
