Document Summary
The po2 of air-equilibrated water is 760torr or 1 atm. False, supposed to be 160 torr, the 760torr is atmospheric pressure not only for o. The solubility of blood for o is higher than that of plasma. In antarctic ice fish, the capacitance and solubility of blood for o2 is equal. In antarctice ice fish, ^^ but with co2. Distinguish between carrying capacity and binding affinity with respect to blood-o2 transport. Cc is how much o2 can bind, total amount in blood, mostly bound to haemoglobin. Weddell seal is a diver --> has a higher carrying capacity than the human. Mackerel are found in high oxygen water, strong swimmers. Carp in low oxygen environment --> high affinity haemoglobin. May have different shapes like hyperbolic and s shaped. When co2 or o2 bind, they shift the protein slightly. Lower co2, lower proton levels, increase ph curve shifts to the left i. Make it easier for oxygen to unload into oxygen f.
