<prompt> CO2 is mainly transported in the blood in which form:Dissolved formHCO3Carbamino compoundGas form  <response>: CO2 is transported in the blood in 3 forms:As HCO3- CO2 is mainly transported in bicarbonate form - 70. When CO2 diffuses into RBC, it reacts chemically with water and with help of enzyme carbonic anhydrase it is converted into HCO3 H CO2 H2O HCO3H As dissolved CO2: 6 - 7 of CO2 transportAs carbamino compound of Hb and other plasma proteins: 20 of C02 transport.
