Predict how oxygen saturation would be affected if an individual has defective hexokinase enzymes.
A) 2,3-BPG levels are elevated and oxygen binding decreases.
B) 2,3-BPG levels are reduced and oxygen binding increases.
C) 2,3-BPG levels are elevated and oxygen binding increases.
D) 2,3-BPG levels are reduced and oxygen binding decreases.

Question

Quizplus · Accepted Answer

Defective hexokinase would lead to decreased glycolysis, reducing the production of 2,3-BPG. Lower 2,3-BPG levels would result in increased oxygen binding affinity of hemoglobin, thus increasing oxygen saturation.
