Igcse Model Questions Vol1 2024 Biology Question 35
Practice objective / multiple choice question 35 from the 2024 Igcse Model Questions Vol1 Biology examination.
Using the labelled diagram of the human respiratory system, the alveolar wall thickness is \(0.5\ \mu\text{m}\) and the total alveolar surface area is \(70\ \text{m}^{2}\). The diffusion coefficient for oxygen is \(2.1\times10^{-5}\ \text{cm}^{2}\,\text{s}^{-1}\) and the partial pressure difference between alveolar air and blood is \(100\ \text{mmHg}\). Apply Fick's law \(\text{Rate}= \dfrac{D \times A \times \Delta P}{d}\) to estimate the rate of oxygen diffusion in \(\text{cm}^{3}\,\text{s}^{-1}\). (Convert all units appropriately.)
