Myoglobin isolated from alligator's muscle is a monomeric protein. It has 3 time stronger affinity for oxygen than human myoglobin with p50 = 1.8 Torr. 1) Use Excell software to make a plot of alligator myoglobin oxygen saturation (Y) as a function of oxygen pressure. (Hint: use pressure values from 0 Torr to 20 Torr and equation Y = pO2/(po2+p50), more information about equation can be found on page 225.
2) At what oxygen pressure is the fractional saturation 75 %. Provide the plot from Excell software, label all axes as appropriate.
