Neco 2024 Biology Question 32
Practice objective / multiple choice question 32 from the 2024 Neco Biology examination.
In the diagram of an alveolar wall, three layers are shown: the capillary wall (0.5 µm thick), the alveolar epithelium (0.2 µm thick) and a thin surfactant layer (0.05 µm thick). Diffusion rate of oxygen is inversely proportional to the total diffusion distance. A disease increases the surfactant layer thickness by 0.15 µm. What is the percentage decrease in the diffusion rate of oxygen caused by this change? Express your answer to one decimal place.
