WebIn the lungs there is a high partial pressure of oxygen, so haemoglobin is rapidly loaded with oxygen How is oxygen unloaded in respiring tissues? When there is a small drop in oxygen levels in respiring tissues oxygen is released rapidly from haemoglobin to diffuse into the cells. Effect is enhanced by low pH in the tissues compared with lungs.
WebProtein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. The protein hemoglobin makes an excellent buffer.
