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"#
