Question

In lungs there is definite exchange of ions between RBC and plasma. Removal of CO2 from blood involves :
(1) efflux of Cl– ions from RBC
(2) influx of Cl– ions into RBC
(3) influx of H+ ions into RBC
(4) efflux of HCO3- ions frm rbc

Answer 1

hey friend

the answer is option 4

hope it is helpful

Answer 2

In lungs there is definite exchange of ions between RBC and plasma of efflux of HCO3- ions from RBC (Red blood cells).

Basically, carbon dioxide is produced in the tissues as a byproduct of the regular metabolism.

This will totally dissolve the blood plasma into red blood cells, where in carbonic anhydrase will catalyze the hydration and turn it into carbonic acid.
