Question

The largest proportion of CO2 carried by blood is in the form of - (A) Molecular CO2 dissolved in the plasma (B) Bicarbonates (HCO3-) carried within RBCs (C) HCO3- carried in the plasma (D) Molecular CO2 chemically bound to haemoglobin

Tardigrade Admin · Accepted Answer

Correct answer is (c) HCO3- carried in the plasma

Q. The largest proportion of $C O_{2}$ carried by blood is in the form of -

Molecular $C O_{2}$ dissolved in the plasma

Bicarbonates $(H C O_{3}^{-})$ carried within RBCs

$H CO 3^{-}$ carried in the plasma

Molecular $C O_{2}$ chemically bound to haemoglobin

Correct answer is (c) $H CO 3^{-}$ carried in the plasma
