Description

How CO2 is transported in humans by blood.

Resource summary

Transport of CO2
1 This comes from a respiring body cell
2 5% is dissolved in the blood plasma
3 10-20% is carried bound to haemoglobin called carbaminohaemoglobin
4 75-85% is as bicarbonate in cells and plasma.
4.1 CO2+H2O
4.1.1 Carbonic anhydrase enzyme
4.1.1.1 Carbonic acid
4.1.1.1.1
4.1.1.1.2 HCO3- and H+
4.1.1.1.2.1
4.1.1.1.2.2 H+ ions transported by Hb as haemoglobinic acid. This, therefore, shows Hb as a blood buffer
4.1.1.1.2.3 HCO3- the reacts with NA +
4.1.1.1.2.3.1 Forms NaCO3
4.1.1.1.2.3.2 Na comes from the NaCl in the blood
4.1.1.1.2.3.2.1 Cl- then diffuses into the cells to compensate for the loss of bicarbonate ions. This is called chloride shift.
4.1.1.1.3 Reversible reaction
4.1.2 Reversible reaction
