Summary Introduction
Introduction:
With no oxygen, hemoglobin (Hb) is found in a tense state, that is, it has less affinity for oxygen. When the oxygen level increases, the binding affinity for hemoglobin also increases. When % (percent) hemoglobin saturation of the y-axis is plotted against the partial pressure of oxygen (mm Hg or millimeter of mercury) on the x-axis, we get an S-shaped curve. This indicates that with an increase in oxygen, more hemoglobin binds to it, which is known as the relaxed state. This phenomenon of oxygen binding readily at the relaxed state of hemoglobin is known as cooperativity. When hemoglobin is 100% saturated with oxygen, the S-shaped curve levels out eventually.

1. The pressure of a gas is inversely proportional to its volume
2. A lower, more acidic pH promotes oxygen dissociation from hemoglobin
3. Hemoglobin saturated with oxygen has a low affinity for carbon dioxide
4. The concentration of a gas in a liquid is directly proportional to the solubility and partial pressure of that gas
5. The total pressure exerted by a mixture of gases is the sum of the partial pressures of the gases in the mixture
