Curve B Below Represents the Oxygen-Hemoglobin Dissociation Curve for Normal $\mathrm { P } _ { \mathrm { o } _ { 2 } }$

Multiple Choice

Curve B below represents the oxygen-hemoglobin dissociation curve for normal body temperature,arterial hydrogen ion concentration,and DPG concentration. $\mathrm { P } _ { \mathrm { o } _ { 2 } }$ (mm Hg)

A) Curve A may represent the dissociation at higher than normal arterial hydrogen ion concentration
B) Curve C may represent the dissociation at lower than normal body temperature
C) Curve A may represent the dissociation at very low DPG levels
D) Both curve A may represent the dissociation at higher than normal arterial hydrogen ion concentration and curve C may represent the dissociation at lower than normal body temperature are correct
E) Both curve A may represent the dissociation at higher than normal arterial hydrogen ion concentration and curve A may represent the dissociation at very low DPG levels are correct
