10. The reaction for cellular respiration is exergonic (AG = -2870 kcal/mol) but only produces 32 ATP per molecule of glucose, representing an energy total of AG = +976 kcal/mol. What can explain this discrepancy? A. One molecule of glucose produces 2 pyruvate during glycolysis and cellular respiration therefore produces a total of 64 ATP. This makes up for the difference in energy converted from glucose to ATP. B. Both NADH and FADH₂ are also produced and contribute to some ATP, on top of the 32 ATP already produced. C. Energy remains in some glucose molecules that are not yet oxidized. D. Energy is lost in the form of heat. E. Cellular respiration includes some endergonic reactions that make up the difference in energy converted from glucose to ATP.

10. The reaction for cellular respiration is exergonic (AG = -2870 kcal/mol) but only produces 32 ATP per
molecule of glucose, representing an energy total of AG = +976 kcal/mol. What can explain this
discrepancy?
A. One molecule of glucose produces 2 pyruvate during glycolysis and cellular respiration therefore
produces a total of 64 ATP. This makes up for the difference in energy converted from glucose to
ATP.
B. Both NADH and FADH₂ are also produced and contribute to some ATP, on top of the 32 ATP
already produced.
C. Energy remains in some glucose molecules that are not yet oxidized.
D. Energy is lost in the form of heat.
E. Cellular respiration includes some endergonic reactions that make up the difference in energy
converted from glucose to ATP.
