The oxygen dissociation curve:

The oxygen dissociation curve, and the role of hemoglobin, are important clinically in understanding the relationship of arterial, oxygen saturation to the partial pressure of oxygen in arterial blood, particularly as it relates to disease.

Which SINGLE statement regarding the oxygen dissociation curve is true?

	Haemoglobin is most attracted to oxygen when 1 of the 4 polypeptide chains are bound to oxygen
	A right shift reduces the oxygen available to the tissues
	The p50 value is the value that tells us the partial pressure of oxygen at which haemoglobin is 50% saturated with oxygen
	Each gram of haemoglobin can combine with 2.68 mL of oxygen
	An increase in pH causes a right shift
