Practice objective / multiple choice question 10 from the 2020 Waec Model Questions Vol1 Biology examination.
At rest a person has an alveolar ventilation of 4 L min⁻¹ and an arterial PCO₂ of 40 mmHg. During moderate exercise the alveolar ventilation rises to 12 L min⁻¹ while the metabolic production of CO₂ doubles. Using the alveolar ventilation equation (PaCO₂ ∝ VCO₂ / VA), estimate the new arterial PCO₂ (in mmHg) during exercise.
