Neco 2020 Biology Question 26
Practice objective / multiple choice question 26 from the 2020 Neco Biology examination.
The diagram of an alveolar-capillary unit shows the following measurements: alveolar membrane thickness = 0.5 µm, capillary wall thickness = 0.8 µm, alveolar surface area = 70 m², capillary surface area = 50 m², partial pressure of O₂ = 100 mmHg and partial pressure of CO₂ = 40 mmHg. Using Fick's law of diffusion (\( \text{Rate} \propto \frac{\Delta P \times A}{d} \)), calculate the ratio of the diffusion rate of O₂ to that of CO₂.
