The molecule of sugar has more energy.

Explanation:

Given that the oxidation of, for example, glucose (C_6H_12O_6) by cellular respiration can produce 38 ATP, it would follow that there is more energy in a molecule of sugar than a molecule of ATP.

DeltaG_("oxidation of glucose")=-686" kcal/mol"

DeltaG_("hydrolysis of ATP")=-7.3" kcal/mol"
