What is the formula to calculate O2 consumption in a frog?
O2 consumption = ∆PO2 * βO2 * V / (t * m)
Calculate the O2 consumption in μmol O2·g⁻¹·min⁻¹ when ∆PO2 = 20.26 - 18.93 kPa, βO2 = 12.52, V = 0.7 L, t = 20 min, and m = 100 g.
0.00582 μmol O2·g⁻¹·min⁻¹
To make the O2 consumption value more intuitive, what value is it converted to per hour?
0.349 μmol O2·g⁻¹·h⁻¹
Given skin gas exchange of 0.34 μmol·g⁻¹·h⁻¹ and lung gas exchange of 1.8 μmol·g⁻¹·h⁻¹, what percentage of total gas exchange occurs across the skin?
15.88%
Learn how amphibians can conveniently demonstrate gas exchange in a laboratory setting using simple components such as an O2 electrode. Discover how August Krogh's studies from the early 1900s contribute to understanding respiratory physiology.
