When the pH turn low (acidification) in salty-marine water so what change of the Hemoglobin dissociation curve? Is respiratory frequency of a marine fish increase when pH turn low than normal?
In acidic conditions (low pH) in marine water, the hemoglobin dissociation curve shifts to the right. This means that hemoglobin has a lower affinity for oxygen, making it easier for oxygen to be released to tissues. As for the respiratory frequency of marine fish, it often increases in low pH conditions as a compensatory response to maintain oxygen supply.
