Dissolved in blood plasma
What law is CO2 transported in Blood?
Law of mass action
Which equation represents the conversion of CO₂ in the blood?
CO2 + H2O CA ⇌ H2CO3 ⇌ HCO3- + H+
What intermediate compound is formed when CO₂ reacts with water?
Carbonic acid (H2CO3)
What does the CA represent in the equation of conversion of CO2 in the blood?
carbonic anhydrase that convert carbon dioxide and water into carbonic acid
What is one main function of converting CO₂ into bicarbonate?
provides an additional way to transport CO2 to the lungs
