Assertion (A): When $P_{c o_2}$ is high and $P_{o_2}$, is low as in the tissues, more binding of carbon dioxide occurs whereas, when the $P_{c o_2}$ is low and $P_{c o_2}$, is high as in the alveoli, dissociation of $CO _2$ from carbamino- hemoglobin takes place.
Reason (R): $P_{c o_2}$, is a major factor that could affect the binding of $CO _2$ with hemoglobin.
Reason (R): $P_{c o_2}$, is a major factor that could affect the binding of $CO _2$ with hemoglobin.
