Hemoglobin #
- A metalloprotein in red blood cells. Transports oxygen from the lungs to the rest of the body, as well as ~25% of the total CO2, as carbaminohemoglobin.
- Marine animals use hemocyanin, which is based off Copper instead of iron. It’s blue when oxygenated! Also carries Nitric Oxide. 96% of Erythrocyte dry content by weight. Haldane effect: Oxygenation/high pH of blood in the lungs displaces CO2, increasing its removal and reducing its affinity. The Bohr effect, which describes what happens to oxygen release because of an increase of CO2, itself caused by low O2 environments, a low Haldane effect. Get it?
