Which of the following events are not primary sources of hydrogen ions during rigorous exercise?
A)ATP breakdown and release of hydrogen ions
B)Increased production of lactic acid
C)Aerobic metabolism of glucose resulting in the production of carbonic acid
D)anaerobic production of 3-phosphoglucose during glycolysis

Question

Quizplus · Accepted Answer

The anaerobic production of 3-phosphoglucose during glycolysis does not directly release hydrogen ions. It ultimately leads to the production of lactic acid, which does release hydrogen ions, but the direct source of the ions is the lactic acid, not the 3-phosphoglucose. The other options, ATP breakdown and release of hydrogen ions, increased production of lactic acid, and aerobic metabolism of glucose resulting in the production of carbonic acid, all directly release hydrogen ions.
