Waec Model Questions Vol1 2017 Biology Question 44
Practice objective / multiple choice question 44 from the 2017 Waec Model Questions Vol1 Biology examination.
In the gills of a fish, the diffusion distance for O₂ is 2.0 µm and the diffusion coefficient of O₂ in water at the gill temperature is 2.1×10⁻⁵ cm² s⁻¹. The O₂ concentration gradient across the membrane is 0.20 mM. Using Fick's law (J = -D·ΔC/Δx), calculate the O₂ flux in µmol cm⁻² min⁻¹ and state whether this flux can meet a required O₂ uptake of 0.50 µmol cm⁻² min⁻¹.
