WebMar 22, 2024 · The enhanced Bohr effect of penguin Hb should improve O 2 transport to working (acidic) tissues, allowing more complete O 2 unloading of the blood. We suggest that this modification works in tandem with increased Hb-O 2 affinity to maximize both O 2 extraction from the lungs and O 2 unloading from the blood, allowing penguins to fully … WebMar 7, 2024 · What is the Haldane effect?
