1.The oxygen consumption of Sabella decreases soon after the concentration of dissolved oxygen in the sea water falls below the value corresponding to air saturation both at 10 and 17° C. Above air saturation at 17° C there is no significant rise in oxygen consumption. JSTOR is part of ITHAKA, a not-for-profit organization helping the academic community use digital technologies to preserve the scholarly record and to advance research and teaching in sustainable ways. [1] [2] [3] Its affinity for oxygen is weaker than that of most haemoglobins.A dichromatic compound, chlorocruorin is noted for appearing green in dilute solutions, though it appears light red when found in concentrated solutions. All Rights Reserved. Request Permissions. It follows that chlorocruorin functions as an oxygen carrier in Sabella at all temperatures and oxygen pressures to which the animals are subjected in nature. Please contact the Royal Society if you find an error you would like to see corrected. The oxygen consumption of Sabella whose chlorocruorin has been converted to carboxychlorocruorin is lower than that of normal worms. Chlorocruorin is an oxygen-binding hemeprotein present in the blood plasma of many annelids, particularly certain marine polychaetes. 4. © 1940 Royal Society Function of Chlorocruorin in Sabella and of Haemoglobin in Lumbricus Fox, H. Munro; Abstract. A NUMBER of invertebrate animals possess blood pigments which are generally assumed to be respiratory, although only in a few instances has a respiratory function been demonstrated experimentally.

This is the case at air saturation of the water and at oxygen concentrations below air saturation both at 10 and 17 degrees C. 3. 2. As such, it may contain errors. The Society’s fundamental purpose, reflected in its founding Charters of the 1660s, is to recognise, promote, and support excellence in science and to encourage the development and use of science for the benefit of humanity. Mathematical notations produced through Infty OCR. This is the case at air saturation of the water and at oxygen concentrations below air saturation both at 10 and 17° C. 3.

The Society has played a part in some of the most fundamental, significant, and life-changing discoveries in scientific history and Royal Society scientists continue to make outstanding contributions to science in many research areas. Series B, Biological Sciences This item is part of JSTOR collection If chlorocruorin does act as an oxygen carrier, it may be that the pigment does not function when a worm is in air-saturated water, but only comes into action in water deficient in oxygen, the amount of oxygen in simple solution in the worm's blood being sufficient for its needs in air-saturated water. 2.

It follows that chlorocruorin functions as an oxygen carrier in Sabella at all temperatures and oxygen pressures to which the animals are subjected in nature. This text was harvested from a scanned image of the original document using optical character recognition (OCR) software. Other functions performed include O 2 storage, CO 2 transport, and transportation of substances other than respiratory gases. Its affinity for oxygen is weaker than that of most hemoglobins. 4.

It follows that chlorocruorin functions as an oxygen carrier in Sabella at all temperatures and oxygen pressures to which the animals are subjected in nature. The fall in oxygen consumption of the animals after treatment with carbon monoxide is not due to an action of the latter on cell enzymes. Chlorocruorin Last updated February 08, 2020 Chlorocruorin.. Chlorocruorin is an oxygen-binding hemeprotein present in the blood plasma of many annelids, particularly certain marine polychaetes. It follows that chlorocruorin functions as an oxygen carrier in Sabella at all temperatures and oxygen pressures to which the animals are subjected in nature.
