Why ATP Yield from Glucose Varies
Captions available
The idea
One glucose molecule's ATP yield varies because the number of hydrogen ions the complexes pump differs between species, and the shuttle moving NADH into the mitochondrion differs between tissues.
In practice
Liver cells shuttle glycolysis's NADH in using NAD+, while brain cells use a shuttle ending in FAD+, yielding fewer ATP.
Where people slip
This range reflects real shuttle-system differences between cells, not an accounting error.
