Which statement truly represents the difference between the two curves?

Curve A represents an haemoglobin that has higher affinity for oxygen at all partial pressures of oxygen

Curve A represents a curve that has higher affinity for haemobloby at only at low partial pressures of oxygen

Curve A represents haemoglobin that will readily release oxygen at all partial pressures

Curve A represents haemoglobin that will not readily bind to oxygen even at high partial pressure of oxygen

Which of the following statements is true from the curve?

any decrease in partial pressure will always cause curve A's haemoglobin to release more oxygen

any decrease in partial pressure will always cause curve B's haemoglobin to release more oxygen

any decrease in partial pressure will only cause curve A's haemoglobin to release more oxygen at low partial pressures of oxygen

any decrease in partial pressure will only cause curve A's haemoglobin to release more oxygen at high partial pressures of oxygen
