During high-intensity exercise, why does arterial Pco2 decrease beyond its usual set point? Arterial Po2 is reduced during high intensity exercise, which stimulates chemoreceptors to increase ventilation beyond current CO2 production. O During high intensity exercise, the blood becomes more alkaline, which leads to more CO₂ being converted to H* and bicarbonate. Anaerobic metabolism does not produce CO2. O Acidic by-products of anaerobic metabolism decrease plasma pH, which stimulates central chemoreceptors to increase ventilation beyond current CO₂ production.
