Question

what is the effect of pco2 on oxygen transport

Answer 1

hey

At the tissues, the high pCO2 and low pO2 favours the dissociation of oxygen from oxyhaemoglobin. Hence, the affinity of haemoglobin for oxygen is enhanced by the decrease of pCO2 in blood. Therefore,oxygen is transported in blood as oxyhaemoglobin and oxygen dissociates from it at the tissues.

Answer 2

hey dear the diffusibility of CO2 into the blood plasma is 20 times more than O2..and that's why if CO2 will increase the diffusibility of oxygen will decrease in blood plasma during oxygen transport .
and oxygen dissociation curve will shifte towards right when CO2 concentration increases.
hope it helps u dear..
