Question

Oxygen transport by hemerythrin, oxygen is bound as

Answer 1

erythrin(also spelledhaemerythrin;Ancient Greek:αἷμα,translit. haîma,lit. 'blood',Ancient Greek:ἐρυθρός,translit. erythrós,lit. 'red') is anoligomericproteinresponsible foroxygen(O2) transport in themarine invertebratephylaofsipunculids,priapulids,brachiopods, and in a singleannelidworm genus,Magelona.Myohemerythrinis amonomericO2-binding protein found in the muscles of marine invertebrates. Hemerythrin and myohemerythrin are essentially colorless when deoxygenated, but turn a violet-pink in the oxygenated state.Hemerythrin does not, as the name might suggest, contain aheme. The names of the blood oxygen transportershemoglobin,hemocyanin, hemerythrin, do not refer to the heme group (only found in globins), instead these names are derived from the Greek wordfor blood. Recent evidence has revealed hemerythrin to be a multi-functional protein – contributing to innate immunity and anterior tissue regeneration in worms.

Evithrin.

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
