Low pH alters hemoglobin structure so that oxygen binds less strongly to hemoglobin at low PO₂.This increases the effectiveness of
A)external respiration.
B)internal respiration.
C)carbon dioxide transport.
D)hemoglobin synthesis.
E)acid-base balance.

Question

Quizplus · Accepted Answer

Low pH (acidic conditions) shift the oxygen-hemoglobin dissociation curve to the right. This means that at the same PO₂, hemoglobin releases more oxygen, facilitating internal respiration, where oxygen is unloaded to the tissues.
