Which molecule is best described as energy rich because of the amount of energy that can be stored in it and released from it?

Glucose, C₆H₁₂O₆, is energy rich because it stores substantial chemical energy in its bonds, which cells can release during cellular respiration. CO₂ is a low-energy product of respiration, and ADP has less stored energy than ATP. Therefore, the best choice is C₆H₁₂O₆.
