Heart and muscle cells, where myoglobin resides, maintains an intracellular pO2 of about 2.5 torr. Calculate the fractional saturation (for human myoglobin) if a small change (1 torr) in oxygen partial pressure occurs in either direction (ie what happens at 1.5 torr, what happens at 3.5 torr?) and explain how a small change in oxygen pressure dramatically changes the myoglobin oxygen binding.
