What is In presence of Haldane effect, CO2 uptake is 2 ml/100ml of blood in arteries, what will be CO2 uptake in absence of Haldane effect in veins- and explain in detail?
Ans. (a) 2 ml/100 ml of blood(Ref: Ganong, 25th ed/p.642)This picture is carbon dioxide dissociation curveAt Po, 100 mm Hg and Pco2 45mmHg,CO2 content in blood changes from 48 ml/dl to 50 ml/dlAt Po2 40mmHg and Pco2 45mmHg,CO2 content in blood changes from 48 ml/dl to 52 ml/dlThe amount of Co2 taken up at tissues is doubled (Point B to Point A) due to Haldane effectIn the absence of Haldane effect, CO2 content in blood changes from 48 ml/dl to 50 ml/dl (difference is 2ml/dl)
