Diagrams For All Topics

Question 1

Diagram of Oxygen Dissociation Curve

Answer 1

-diagram showing normal oxygen dissociation curve.
-diagram showing curve with increased CO2 to the right
-both axes correctly labelled
c. sketch/statement of S-shaped «oxygen dissociation» curve
-axes of graph labelled correctly as percentage oxygen saturation of hemoglobin on y-axis AND partial pressure of oxygen on x-axis
-curve shifted to right (and lower) for higher partial pressure /concentration of CO2 /lower pH
