   Complete oxidation of palmitate (16 carbons) yields about 106 molecules of ATP, whereas glucose yields about 30. Which comparison is correct per carbon atom?
   1. AGlucose yields more per carbon, because it enters the Krebs cycle directly
   2. BThe two are identical per carbon
   3. CPalmitate yields less per carbon, because activation costs two ATP equivalents
   4. DThe comparison cannot be made, since the pathways are different
   5. EPalmitate still yields more ATP per carbon, because its carbons start out more reduced
