Carbon Dioxide Transport
5% transported in plasma as CO2 - simple diffusion
10% transported as carbamino-haemoglobin - CO2 + amino acids + haemoglobin
85% transported as HCO3- ions:
- CO2 diffuses into the red blood cell
- CO2 + H2O -> H2CO3 (carbonic acid) - catalysed by carbonic anhydrase
- H2CO3 -> H+ + HCO3-
- HCO3- ions diffuse into plasma makes red blood cell…
