Overview Forms of Carbon Dioxide (CO2) in the Blood Dissolved CO2 Bicarbonate (HCO3-) Carbaminohemoglobin ~5-10% of total CO2 content 70% of total CO2 content 20-25% of total CO2 content CO2 bound to N-terminus amino group of hemoglobin (Hb) Stabilizes taut form of Hb → right-shift of O2-Hb dissociation curve (Bohr effect) → favors O2 release Transport of CO2 in blood (peripheral tissues → RBC → lungs) login to view 40 more bullets
