Assertion. CO_(2) is carried in the plasma mainly as HCO_(3)^(-) ions Reason. Zinc -containing enzyme carbonic anhydrase of RBCs catalyses the formations fo HCO_(3)^(-) ions that enter plasma.

What percent (%) of CO_(2) is transported as bicarbonate (HCO_(3)) with the help of the enzyme carbonic anhydrase?

Assertion : At the tissue level, 70 percent of CO_(2) formed from contabolism is trapped as bicarbonate in the RBCs. Reason : At tissue level, carbonic anhydrase in RBCs facilites the formation of CO_(2) and H_(2)O from bicarbonate.

Assertion :- Carbonic acid is more formed inside the RBC's than the plasma. Reason :- An enzyme carbonic anhydrase is present inside the RBC's

Assertion CO_(2) transport occurs very fast through RBCs. Reason : Enzyme carbonic anhydrase is absent in blood plsama.

Assertion: RBCs contains a very high concentration of the enzyme, carbonic anhydrase and minute quantities of the same is present in the plasma too. Reason: Carbonic anhydrase catalyse the formation of carbonic acid from H_(2)O" and "CO_(2)

A : Temporary hardness is due to HCO_(3)^(-) ions. R : permanent hardness is due to CaCl_(2)

Which factor in tissues favours the formation of HCO_(3)^(-) and H^(+) ions in the blood?
