Vedclass · Answer

(D) In the alveoli,the partial pressure of oxygen $(pO_2)$ is high and the partial pressure of carbon dioxide $(pCO_2)$ is low.According to the Haldane effect,the binding of oxygen to hemoglobin in the lungs promotes the dissociation of $CO_2$ from carbaminohemoglobin.High $pO_2$ facilitates the oxygenation of hemoglobin,which displaces $CO_2$ from the carbamino compounds.Low $pCO_2$ in the alveoli creates a concentration gradient that allows $CO_2$ to diffuse out of the blood and into the alveoli for exhalation.Therefore,the conditions $pCO_2$ low and $pO_2$ high are necessary for the dissociation of $CO_2$ from carbaminohemoglobin.

What conditions in the alveoli favor the dissociation of carbon dioxide from carbaminohemoglobin?
