CO 2 Transport and buffering Study Guide 1. Broad question: How is the CO 2 produced during a VO 2max test? Describe the VCO 2 curve relative to VO 2 below lactate threshold and above lactate threshold. Explain why the curve looks the way it does (relative to VO 2 ) The CO2 output during a VO2 max test is below VO2 until the lactate threshold where CO2 increases more rapidly than O2 uptake. Ventilation increases in proportion to the increased CO2 output. 2. Make sure you understand how CO 2 is transported in blood, and how the H+ ions from glycolysis are buffered. What is the breathing consequence of H+ ion buffering? Below lactate threshold the CO2 load in the blood is due to the increasing metabolic activity of the mitochondria. Above the lactate threshold the CO2 is generated by the bicarbonate buffering of the H+ ions that are being produced as pyruvate is being converted to lactic acid. This is an additional CO2 load that supplements the metabolic production of CO2 in the mitochondria. 3.
