The potential diagram for oxygen at ph 7
Webb13 nov. 2024 · Oxygen Delivery at Tissues. As shown on the diagram above, the percentage of oxygen bound to haemoglobin is related to the partial pressure of oxygen (pO 2) at a given site.When oxyhaemoglobin reaches a tissue with a low pO 2 (e.g. skeletal muscle), it will dissociate into oxygen and haemoglobin, resulting in an increase in local pO 2.When … Webb1 juli 1988 · Redox potentials at pH 7 for one-, two- and four-electron couples involving these states are presented as a potential diagram.
