How does the oxidation of one glucose molecule compare to the oxidation of palmitic acid (palmitate)?
Both generate ATP.
The oxidation of one glucose molecule yields about 34 ATP, whereas the oxidation of palmitic acid (palmitate) yields 129 ATP.
The respiratory quotient (RQ) of glucose is
The RQ of palmitic acid is
A lower RQ means that more oxygen is consumed relative to the production of carbon dioxide, which means that more ATP can be produced.
